In this tutorial the instructor shows a method to compute the interior angle sum of a polygon. He gives us the formula for the interior angle sum of a convex polygon as (n-2) * 180 where n is the number of sides of the polygon. He goes and take a 6 sided polygon as an example and does the math by substituting the value of 'n' in the equation and arrives at the result. This video clearly gives the formula and demonstrates with an example of how to calculate the sum of interior angles of a poly...

Omar, Hayley, Gary, and Autumn teach us how to use a protractor. They give a bit of information from About.com on the history of protractors. They are used to measure angles. The first protractor was used to help with navigation and invented in 1801. To measure an angle, line up the base of the protractor with 1 line of the angle. The center circle should be on the vertex of the angle. Use the "swivel thing" to find what degree the other end of the angle lines up with. If there isn't one, you...

This video shows you how to easily find the area of a triangle when you know the length of 2 sides and the angle between them. The first thing you have to do is mark the sides of the triangle by a, b, c, where a is the side between A and B, b is the side between B and C and c is the side between C and A. If you know 2 of these 3 sides an you know the angle between them you can find the area of the triangle very simple: Area= (a x b x sin c)/2, where a, b are the two sides and c is the angle b...

When a triangle is inserted in a circle in such a way that one of the side of the triangle is diameter of the circle then the triangle is right triangle. To prove this first draw the figure of a circle. Now draw a diameter to it. It can be any line passing through the center of the circle and touching the sides of it. Now making this as the side of a triangle draw two lines from the ends of the diameter to a point on the circle. Now join the center of the circle to the other vertex of the cir...

In this video, Robert Ahdoot becomes "surfer dude" and shows us the ways of deductive reasoning, as relating to geometry. He begins with a simple example of a syllogism, taking two premises and using them to form a conclusion. This is called the Law of Syllogism. This concept is then used for geometric statements. If two angles are complementary, they sum to 90 degrees. If two angles sum to 90 degrees, then they are acute. By the law taught, it can be said that if two angles are complementary...
Taylor Erkkinen, co-owner of the Brooklyn Kitchen, shows how to properly hone a knife Hold a butcher steel vertically. Place it on a towel on a flat surface in order to anchor and hold it in place. Most knifes are sharpened to 20 degrees. To find this angle, hold the knife perpendicularly to the butcher steel--this is 90 degrees. Reducing to half that angle is 45 degrees, and half of that angle is 22 degrees. Pass the knife equally on each side of the butcher steel, making sure you run all th...
This video describes the properties of a parallelogram. It states that it is a quadrilateral, meaning that the four angles inside have to add up to 360 degrees. Both sides of the parallelogram are always going to be parallel. Also, both sides are congruent, as well as the opposite angles. It also has two diagonals that intersect at a midpoint. This video will teach you the main properties of a parallelogram and help you better understand its angles and the physical makeup of it.
In this video the author shows us how to find the measure of a central angle when its corresponding arc degree is given. He shows how to solve this kind of problem by solving an example.
