Hypotenuse Calculator - Calculate Hypotenuse Length for Right-angled Triangle

The Hypotenuse Calculator is used to calculate the length of the hypotenuse of a right-angled triangle.

Pythagoras’ theorem relates the lengths of the sides of a right-angled triangle. In any right-angled triangle, the side opposite the right-angle is called the hypotenuse. If the length of the hypotenuse of a right-angled triangle is c and the lengths of the other sides are a and b; the Pythagoras’ theorem states that the square of the hypotenuse, (c2), is equal to the sum of the squares of the other two sides, (a2 + b2).

To find the hypotenuse, add the squares of the other sides, then take the square root.

To find a shorter side, subtract the squares of the other sides, then take the square root.
