What is the Pythagorean Theorem?

The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) equals the sum of the squares of the other two sides. The formula is: a² + b² = c²

This calculator allows you to find any missing side of a right triangle by entering the two known sides. It's one of the most fundamental theorems in geometry and has countless applications.
