Called the hypotenuse in a right triangle the side lying opposite the right angle.
The hypotenuse is the longest side in a right triangle.
The remaining sides in a right triangle are called legs.
You will need
- Basic knowledge of geometry.
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, to be squared and the length of the legs folded.
The length of the hypotenuse is equal to the square root of the square of its length. To find its length, take the square root of a number, equal to the sum of the squares of the legs. The resulting number is the length of the hypotenuse.
