About the Pythagorean Theorem — Math Calculator
The Pythagorean Theorem is a fundamental relation in Euclidean geometry. It states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Formula & Calculation Method
The standard mathematical relationship used for this calculation is:
Worked Step-by-Step Example
For a right triangle with sides a = 3 cm and b = 4 cm: c = √(3² + 4²) = √(9 + 16) = √25 = 5 cm.
How to Use
- Identify the two sides of the right triangle you already know.
- Enter their values in the input fields.
- The calculator solves for the third missing side length automatically.
