A hypotenuse is a side in a right-angled triangle that lies opposite a right angle.

Hypotenuse is the longest side in a right-angled triangle.

The other sides in the right-angled triangle are called the legs.

You will need

• Basic knowledge of geometry.

Instructions

1

The square of the length of the hypotenuse is equal to the sum of the squares of the legs. That is, to find the square of the length of the hypotenuse, it is necessary to square the length of the legs and fold them.

2

The length of the hypotenuse is equal to the square root of the square of its length. To find its length, extract the square root of the number equal to the sum of the squares of the legs. The resulting number will be the length of the hypotenuse.
