In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to the Pythagoras theorem. Perpendicular, Base, and Hypotenuse are the names of the angles that make up this triangle. As it is perpendicular to the angle, the hypotenuse in this case is the longest side. When squared, the sides of a right angle (let's say a, b, and c) with positive integer values are entered into an equation known as a Pythagorean triple.
