How do you find the hypoteneuse of an isosceles right triangle?

It is very unlikely for a right angle triangle to be isosceles, however it is possible if the angles are 90, 45, and 45 degrees. It does not matter if the triangle is isosceles, this method works for all right triangles. The following formula is your answer, when h=hypotenuse, and a and b are other two sides. a2 + b2 = h2
