Pythagorean Theorem

• A right triangle is a triangle with one right, 90°, angle. It has two legs, which are the shorter sides. The hypotenuse is the longest side and is the diagonal; it‘s the side across from the right angle.
• The Pythagorean Theorem, a² + b² = c², shows how the lengths of the sides in a right triangle are related. The sum of the squares of the legs is equal to the hypotenuse.
• The letters a, b, and c are commonly used to represent the sides of a right triangle. a and b are used to represent the legs and c is used to represent the hypotenuse.
