Pythagorean Theorem Calculator is a free online tool that displays the value of the unknown variable when the other two sides of the right-angle triangle are given. This tool provides a quick and accurate calculation, displaying the result in seconds.

How to Use the Pythagorean Theorem Calculator?

Steps to Use the Calculator:

1. Enter the values of two sides in the input fields.

2. The hypotenuse will be computed and displayed automatically.

What is the Pythagorean Theorem?

The Pythagorean Theorem states that 'In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides.' It defines the three sides of a right triangle: the perpendicular side, adjacent side (base), and the hypotenuse side. This theorem is mainly used to determine the length of the legs and the hypotenuse side.

Standard Formula

The standard formula to represent the Pythagorean Theorem is:

Perpendicular² + Base² = Hypotenuse²

(or)

a² + b² = c²
