Pythagorean Theorem




Pythagorean Theorem Calculator is the best way to find measures of the hypotenuse or one side of the triangle. Get results with steps thanks to our tool online.

Pythagorean Theorem Calculator: Steps to Resolve Equation

To help you to use our Pythagorean Theorem Calculator, we have drawn a triangle with 3 sides. We allow you to calculate the hypotenuse or one of the other side. To make your calcul easy, we set only one other side: the (b). But don’t worry if your side (b) is longer than the (a). Just enter your values and enjoy results.

How to Use the Right Triangle Calculator?

  1. Choose the expected result: Hypotenuse (c) or other side (b)
  2. Enter your measures: (a) and (b) for hypotenuse or (a) and (c) for the other side
  3. Click on “calculate” and get result with steps.

Pythagorean Theorem Calcul with Steps

Calculation formula for hypotenuse is:

  • c² = a² + b²
  • c = √(a² + b²)
  • If: a = 45 et b = 4
  • Then: c² = 45² + 4²
  • So: c = √(45² + 4²)
  • c = √(2025 + 16)
  • c = √2041
  • c = 45.18
