Pythagorean Theorem Calculator
Enter any two sides of a right triangle and leave the unknown side blank. The calculator solves for side A, side B, or hypotenuse C, or verifies whether all three sides form a right triangle.
Instructions
Enter any two sides of a right triangle and leave the unknown side blank. A and B are the legs. C is the hypotenuse and must be the longest side.
If all three sides are entered, the calculator verifies whether they form a right triangle. Example: A = 3, B = 4, and C = 5 satisfies 3² + 4² = 5².

Explanations
The Pythagorean theorem relates the two legs of a right triangle to its hypotenuse: A² + B² = C².
A and B are the legs. C is the hypotenuse and must be the longest side.
Enter any two side lengths and leave the unknown side blank. If all three sides are entered, the calculator checks whether they form a right triangle.
Example: with A = 3 and B = 4, C = √(3² + 4²) = √25 = 5.
