7-3 Special Right Triangles

45°-45°-90° Triangle Theorem (Thm 45°-45°-90° Triangle Theorem (Thm. 7-8) In a 45°-45°-90° triangle, both legs are congruent and the length of the hypotenuse is 2 times the length of the leg. hyp = 2 • leg

30°-60°-90° Triangle Theorem (Thm 30°-60°-90° Triangle Theorem (Thm. 7-9) In a 30°-60°-90° triangle, the length of the hypotenuse is twice the length of the shorter leg. The length of the longer leg is 3 times the length of the shorter leg. hyp = 2 • short long = 3 • short
