FAQ

The following is the calculation formula for the length of the hypotenuse of a right-angled triangle, based on the Pythagorean theorem:

where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

The Pythagorean Theorem states: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

Enter a and b then click Calculate Hypotenuse button. Please note you should enter numbers greater than 0.
