Hypotenuse-Leg (HL) Theorem: If the _______________ and one ______ of one RIGHT triangle are congruent to the hypotenuse and one leg of another ___________ triangle, then the triangles are congruent! hypotenuse leg right • To use the HL Theorem, you must know/show: • There are two right triangles • The triangles have congruent hypotenuses • There is one pair of corresponding congruent legs
