Find the hypotenuse of a right triangle with this pythagorean theorem calculator.

## How do you get the hypotenuse from the pythagorean theorem?

To calculate the hypotenuse, use the pythagorean theorem as follows:

A^{2} + B^{2} = C^{2}

A and B are the lengths of the legs of the triangle. C is the hypotenuse.

Example: A right triangle with a length of Leg A as 50 inches and a length of Leg B as 50 inches has a hypotenuse of:

50^{2} + 50^{2} = C^{2}

C^{2} = 5000

C = 70.7107 inches
