Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.
We start with a right triangle. A right triangle is a three sided figure with one angle equal to 90 degrees. A 90 degree angle is called a right angle and that is where the right triangle gets its name. We define the side of the triangle opposite from the right angle to be the hypotenuse, h. It is the longest side of the three sides of the right triangle. The word hypotenuse comes from two Greek words meaning to stretch, since this is the longest side. We are going to label the other two sides a and b. The Pythagorean Theorem is a statement relating the lengths of the sides of any right triangle.
