How to Calculate Pythagorean
What is Pythagorean?
The Pythagorean theorem states that in any right triangle, the square of the hypotenuse equals the sum of squares of the other two legs: a² + b² = c².
Step-by-Step Guide
- 1Identify the hypotenuse — always the side opposite the 90° angle
- 2Square both legs: a² and b²
- 3Add: a² + b²
- 4Take the square root to find c, or rearrange to find a missing leg
Worked Examples
Input
a=3, b=4
