Then find the square root of c² to get the length of the hypotenuse. Basically the hypotenuse is the property of only the right triangle and no other triangle. Input the two lengths that you have into the formula.
The Pythagorean Theorem only works on right triangles and by definition only right.
This can help you find any missing side. It asserts that the sum of the squares of the lengths of the shorter two sides of the triangle a and b is equal to the square of the length of the hypotenuse c. A2 b2 c2 a2 b2 c2. The Hypotenuse of a Triangle Formula.
