Hypotenuse calculator

Calculate the length of the hypotenuse of a right-angle triangle.

What is hypotenuse

Hypotenuse it's the longest side of a right-angled triangle, the side opposite the right angle.

How to find hypotenuse

To find hypotenuse use a formula below:

c = √(a2 + b2)

Where:

  • a - side of right triangle
  • b - side of right triangle
  • c - hypotenuse

For example, let's find hypotenuse where a is 5 and b is 10

c = √(52 + 102) = √(25 + 100) = 11.18
