# Find the length of a right triangle

The height of a right triangle can be calculated, given the length of base and height of a right triangle formula can be calculated using the Pythagoras theorem as, (Hypotenuse) 2 = (Height) 2 + (Base) 2. Substitute the known values and ## The Pythagorean Theorem

Right Triangle Shape A = angle A a = side a B = angle B b = side b C = angle C c = side c K = area P = perimeter See Diagram Below: h a = altitude of a h b = altitude of b h c = altitude of c *Length  3 Ways to Find the Length of the Hypotenuse

To find the hypotenuse of a right triangle, use the Pythagorean Theorem. Start with the two known sides and use the famous formula developed by the Greek mathematician
