4.6 Congruence in Right Triangles Objective: I will prove right triangles congruent using the Hypotenuse-Leg Theorem
Vocab: • Hypotenuse: the side opposite the right angle, or the longest side of a triangle • Legs: two shorter sides of a triangle Leg hypotenuse Right Angle Leg
Theorem 4-6: Hypotenuse-Leg (HL) Theorem If the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, the then triangles are congruent If: Then: ABC and DEF are right s and ABC DEF AC DE and CB DF D C A B F E
Key Concept…Conditions for HL Theorem 1. There are 2 right triangles 2. The triangles have congruent hypotenuses 3. There is one pair of congruent legs
