, Right Triangle

A right triangle is a triangle that contains one 90° angle. The two sides that form the right
angle are called the legs, and the side opposite the right angle is called the hypotenuse.
The hypotenuse is always the longest side of a right triangle.

Pythagorean Theorem

The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is
equal to the sum of the squares of the other two sides.
