The hypotenuse of a 30-60-90 triangle is twice as long as the shortest side. The Pythagorean theorem says that in a right triangle, the hypotenuse is equal to the sum of the two legs. The hypotenuse of a 45-45-90 triangle is twice as long as one of the legs. In a triangle, if , then the triangle is obtuse.
