Calculate Hypotenuse of a Triangle

Enter the 2 shortest sides of a right angled triangle (with an angle of 90 degrees) to calculate the third longest side (hypotenue).

Enter value of one side :

Enter value of other side :

What is the Hypotenuse Calculator?

A hypotenuse calculator is an online tool that can be used to determine the hypotenuse (longest side) of a right-angled triangle (90deg). There are two sides that must be entered that relate to the degrees corner.

The hypotenuse has a formula: c=√(a² + b²), Here:
  • a= side of a right triangle
  • b= side of the triangle
  • c= is the length of Hypotenuse

How to use the Hypotenuse Calculator?

To calculate the hypotenuse of a triangle, you simply enter two parallel sides (a and b) that adjoin a triangle's 90-degree corner. Using the specification provided, we can determine the hypotenuse of a right triangle without the missing side.
  1. Insert the A-side of the right-angled triangle into the input box.
  2. Enter the B-side of the right-angled triangle.
  3. Once you enter both sides of the right-angled triangle. (with an angle of 90 degrees). You will get the result of the hypotenuse.
Example: A+B ( 25+55) = Hypotenuse (59.61543424)

What is the Formula to calculate Hypotenuse?


Hypotenuses can be calculated using the formula: ( a2 + b2 = c2 )
Where C is the length of the hypotenuse. The other two sides of the right-angled triangle are A and B.
