Pythagorean Theorem 

The theorem that indicates that a triangle with a 90° angle in it will have sides that measure in a particular equation. The equation is a2+b2=c2. In this equation, c is the length of the side opposite the right angle. The sum of that side, also called the hypotenuse, is equivalent to the sum of the squares of the other two sides, a and b are the lengths of those sides.
