Calculate Hypotenuse
Enter the 2 shortest sides of the right triangle to calculate the hypotenuse and longest side of a right-angled triangle.
How to find the hypotenuse of a triangle?
The hypotenuse is the longest side of a right-angled triangle. A right-angled triangle is a triangle with 3 sides and an angle of 90 degrees. The hypotenuse is always on the opposite side of the right angle.
To calculate the length of the hypotenuse we can use the Pythagorean theorem. Pythagorean theorem is the relation between the length of the different sides of a right triangle.
Formula Hypotenuse
c = √(a² + b²)
In the formula C is the hypotenuse. A and B are the 2 shortest sides that are directly connected to the right angle of 90 degrees.
You can use the Hypotenuse Calculator to quickly calculate the Hypotenuse of your triangle, where you only have to enter the length of the two shortest sides.

The formula to calculate the hypotenuse of a right triangle is c = √(a² + b²). In the formula C is the hypotenuse and A & B the short sides of the triangle. The formula only works for triangles that are right-angled (angle of 90 degrees).
JavaScript has a built-in function to calculate the hypotenuse "Math.hypot()". For more information about this function you can visit MDN Math.hypot().
