Brief Explanations Of Basic Triangle Terms

Friday, February 26th, 2010

The most basic definition of a triangle is that it is a geometric shape that has three sides. If all sides are the same length, then it is called an Equilateral triangle. There are other possibilities for different triangle shapes, depending on the lengths of each of the three sides and the angles.

Following is a basic list of some triangle types.

Some Types of Triangles:
Acute
Equilateral
Isosceles
Obtuse
Right
Scalene

A Brief Description of Each Type:
In an Acute triangle, all three angles are less than 90 degrees.

In an Equilateral triangle, all sides have the same length, with equal angles that are always 60 degrees.

In an Isosceles triangle, two sides measure the same in length and there are two equal angles.

An Obtuse triangle has one angle that is greater than 90 degrees.

A Right triangle has the characteristic of having one 90 degree angle. One of the sides is called a hypotenuse, which is the longest side and is also the side opposite to the right angle.

In a Scalene triangle, all sides do not measure the same and there are no equal angles.

At times, a triangle will have more than one of these types within that triangle, so it will have a combination of the two names as a type, for instance, a Right Isosceles Triangle.

Formulas
There are various formulas for figuring the area or height of a triangle, using vectors, trigonometry, coordinates, Heron’s formula, Pick’s Theorem.

Trigonometry
In Trigonometry the Sine, Cosine and Tangent functions are a side of a triangle divided by another side of the same triangle. Each side has a name, for example, a right-angled triangle has an adjacent side, a hypotenuse side and an opposite side.

Geometry
What does geometry have to do with triangles? Geometry is about shapes and the properties of each shape. Plane Geometry is about flat shapes, so if you drew a triangle on a piece of paper, that would be an example of plane geometry. The other type is Solid Geometry, which, in relation to triangles, would be a triangle that is three dimensional.

Within the Solid Geometry type, there are other categories and sub-categories; in Polyhedra, there are Platonic Solids, Prisms and Pyramids (which have flat surfaces). Relating more to shapes other than the triangle, in Solid Geometry there are also Non-Polyhedra shapes, divided into categories of the cone, cylinder, sphere and torus (where any surface is not flat).

All triangles are convex and bicentric. The name convex is used for polygons, which are either convex or concave. The term bicentric means that the shape has both an incircle and a circumcircle. An incircle is a circle that touches each of the triangle’s three sides (this circle is inside the triangle, with the edge of the circle touching the inside edges of each of the triangle sides). A circumcircle is a circle that passes through each of the triangles three vertices (this circle is on the outside of the triangle, with the three points of the triangle touching the inside edge of the circle).

The term vertices is the plural of vertex. The meaning of vertex is a corner point of any 3-D shape.

These are just the basic terms used in math, geometry and trigonometry in relation to the triangle shape. If you have an interest in the subject, there is much more that you can explore. Your local library is likely to have some good books on this topic.

Stress Education And You Get 83 Percent College Attendance

Wednesday, February 24th, 2010

One of the most nerve-racking days in South Korea just happened. Nearly 700,000 high school students took the national college entrance exam. This is no small ordeal. The once a year test determines a student’s future. There is so much value placed on the exam that planes can’t even fly near the test site, and the workday begins 60 minutes later so students can get to the testing center without any problems.

Police even guide girls toward their school. There are 1,100 assessment locations throughout the nation. Lots of parents usher their children to the test and encouragethem while others stay outside and observe their students taking the test. Students even come equipped with water bottles and cushions to sit on.

Students practice for this test their entire life. One student revealed that they studied six hours per day outside of school in order to prepare. The stress is high because that’s what colleges look at. One student said “It’s all going to be changed by this.”

The constant worry gets so high for some students that they end up taking their own lives. For those that have opted to take the test and spent a large percent of their time studying have parents and relatives praying at Buddhist temples in Seoul and all through the country. Parents pray their child’s college placement exams will turn out well and the scores will be great. Some parents have been praying for this in excess of 100 days.

A students future careers and ultimately their existence comes down to a single test on a single day. Because the country does emphasize education 83 percent of high school grads go to universities. But in order to get to a university they have to score well on the nine hour long test.

The stress and pressure placed on these kids is huge. A child’s future shouldn’t depend on one day and one test. Plus the fact that many kids don’t test very well. It goes back to the idea that people learn and test differently. Some do great on tests while others do better on interviews or projects. The government ought to give students more of a chance to show that they can be flourish in life without this test.

Even though South Korea’s graduation rates are super high, and their college attendance at 83 percent students still need to be able to have a life. They need to use up time with friends socializing, playing sports, and spending time with family. Not everything can be learned in the classroom. They need to experience high school and College life because for many of us that was the greatest time of our life.

There is way too much pressure placed on these South Korean students. The U.S. also has a valuable test but there isn’t as much stress involved. While the SAT and ACT in America are the big test they don’t determine your potential. They give a background to display what you have learned. Yet students can go on to college and live a successful life with the value of hard work and even if you have low scores many still get into college.

Education is terribly important but many Americans go on to college, open their own businesses, and lead successful lives even if they didn’t do well on the test. While the American system isn’t the greatest and there is a lot of room for improvement, the South Koreans need to loosen up a little bit. There is no way one test can establish the intelligence or value of a student.

How To Acquire PhD Level Without Restricting Your Regular Work Assignment

Thursday, February 18th, 2010

Distance learning for a PhD can make a huge difference in your profession. Because many people cannot have the funds for to take some time off of work in order to pursue higher education, distance learning eliminates the inconvenience of traveling to a college or university without sacrificing the quality of education. On the other hand, there are some points that you will want to bear in mind if you desire to try distance learning.

An important thing to remember is that when you participate in a distance learning program targeting a PhD, you have to be devoted. Just like going to a an institution in your area, it’s up to you that you attend any virtual classes and do your study. There won’t be refunds if you’re lagging and do not desire to do the class material. Unlike institutions in your region, you will not be chased by your instructors. There is certainly both an unmentioned agreement plus a written one that you’re responsible for your classwork without chance for refund. If you have bought a number of classes in advance that you will not be able to take part in, refunds are then offered, however only for courses you haven’t yet started.

There are some cases where distance learning for a PhD must be augmented by attending an effective college or university. Medical fields requiring lab time is a good example of this. As you will take most of the supplementary courses through distance learning, the laboratory work and practice should be completed on the field or at a school. If you are pursuing distance learning in a medical field or an additional area that requires hands on practical knowledge, ensure you can get admitted into a local university throughout your credits. Many distance learning programs have transferable credits. When you should transfer your credits, you should make sure that the actual institution you’re attending is supported by the decks of higher education.

If you choose the best school for you, distance learning for a PhD can save you a substantial amount of money while providing you the freedom setting your individual tempo. Distance learning programs, with the exclusion of a couple of group courses, permit you to work whenever it is good for you. As distance learning for a PhD is specific towards the professional, most of the group exercises that take part in these programs are in the evenings, allowing most people to attend.

Getting The Most Out Of Base Ten Blocks For Concept Based Instruction.

Monday, February 1st, 2010

“There is a great danger in the present day lest science- teaching should degenerate into the accumulation of disconnected facts and unexplained formulae, which burden the memory without cultivating the understanding.” ~J. D. Everett [In the preface to his 1873 English translation of Elementary Treatise on Natural Philosophy by A Privat Deschanel. (D. Appleton and Co.)]

Sadly this is EXACTLY what has happened with mathematics education. The whole of mathematics has been broken down into tiny parts and because of this the whole picture is little understood. The more I am forced to teach out of text books whose well meaning authors have fragmented math beyond the basic operations into such disjointed parts that students basically memorize enough to past the test and then forget it, the more I see this is true. This is compounded by teachers who are pressured into “teaching for the standardized tests” not teaching for deeper understanding. The students understand it well enough to pass the test…often with a low “C”.

Crucial concepts like, math is a language, numbers are made up of other numbers, and all we can do with math is count, are lost. Concept based teaching using manipulatives makes math fun and easy and highly understandable, to the point that even very young children can do so called “higher math” with ease. Find Crewton Ramone’s Blog Of Math and there you will see six and seven year old students doing algebra, making change for $100.00, videos and more. Best of all they don’t know it’s difficult.

The idea is to teach math like a language, using basic concepts that build a solid foundation for the next set of concepts that build a solid foundation for the next set of concepts and so on. Working your way through math using concepts that increase in degree of difficulty slowly but surely while the student is in a situation where they cannot fail is a sure fire method for success. Because most concept based teaching uses manipulatives and because text does not lend itself to mathematical notation trying to describe it in detail in a short article like this is like trying to describe blue to a blind man. You have to see it to really get a grasp of what I’m talking about. There are several systems that you might look into to assist in he math education of your child. Any Montessori based system like Mortensen More than Math or Math-U-See will generally be concept based, but the primary complaint I hear from parents and teachers especially with Mortensen Math is that they don’t know how to use these systems. This is often the case with many base ten manipulative sets: they don’t come with enough instruction so that they can be used to their fullest extent.

At Crewton Ramone’s House of Math you can SEE how to use base ten blocks to do a whole lot more than just teach counting. You will find many concept based lessons for teaching basic operations, algebra and more that can be used with any set of base ten blocks.
