How the Pythagorean Theorem Calculator Works

Our Pythagorean theorem calculator is a tool for solving for a side of a right triangle using the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. The formula is: a² + b² = c².
