Hypotenuse of a right triangle

The hypotenuse of a right triangle is the triangle's longest side; the side opposite the right angle.

The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypothenuse equals the sum of the squares of the lengths of the two other sides.
