Pythagorean Triple3 whole numbers that form a right trianglec^2=a^2+b^2Forms a right trianglec^2>a^2+b^2Forms an obtuse trianglec^2<a^2+b^2Forms an acute triangleIsosceles Right Triangle (45-45-90 Triangle)Both legs are congruent, and the length of the hypotenuse is rad2 times the length of a leghypotenuse=rad2 * leg45-45-90 Triangle30-60-90 TriangleThe length of the hypotenuse is twice the length of the shorter leg. The length of the longest leg is rad3 times the length of the shorter leghypotenuse=2 * shorter leg30-60-90 Trianglelonger leg=rad3 * shorter leg30-60-90 Triangle
