4-6 Congruence in Right Triangles M.11.C.1 2.9.11.B Objectives: 1)To prove triangles congruent by the HL Theorem.

Vocabulary **ONLY IN RIGHT TRIANGLES Hypotenuse- Side opposite of the right angle, its the longest side. Legs – the two sides that surround the right angle.

Hypotenuse-Leg (HL) Theorem If the hypotenuse and the leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.

Example Which two triangles are congruent by the HL Theorem? Write a congruence statement.

Example Can you prove the two triangles are congruent using the HL Theorem?

Example: Yes/No Congruency
