How to Calculate Pythagorean Theorem

Find the missing side of a right triangle using a² + b² = c².

The Formula

a² + b² = c²

The pythagorean theorem formula uses the mathematical relationship: a² + b² = c². Each variable in the formula represents a measurable quantity that affects the final result.

Step-by-Step Method

  1. 1Identify all input values needed for the pythagorean theorem calculation.
  2. 2Substitute your known values into the formula: a² + b² = c².
  3. 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
  4. 4Check that your result has the correct units and is within a reasonable range.
  5. 5Verify using the interactive Pythagorean Theorem Calculator to confirm your answer.
