What is a Hypotenuse Calculator?

Hypotenuse Calculator is an online tool where you can quickly calculate the hypotenuse (longest side) of a right angled (90deg) triangle by entering the 2 sides that are connected to the 90 degrees corner.

The Hypotenuse is calculated with the following formula: c = √(a² + b²). Hereby is C the hypotenuse. A and B are the 2 shortest straight sides of the triangle.

How to use the Hypotenuse Calculator?

You can use the online Hypotenuse Calculator by entering the 2 sides that are next to the 90 degrees corner of the triangle.

The hypotenuse is the longest side of the triangle, but only for right angled triangles.
