1. Congruence in Right Triangles Chapter 4 Section 6

2. Objective Students will prove right triangles congruent using the Hypotenuse-Leg- Theorem

3. Right Triangle Leg Hypotenuse

4. Always opposite the right angle of a right triangle The longest side of the triangle

5. Legs Legs are the sides that create the right angle The two shorter sides of the right triangle

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

7. Turn to Page 259… Look at the proof of Hypotenuse Leg Theorem Copy the Key Concept Chart on the bottom of that page.

8. Turn to page 260… Look at Problem 1 and 2 Try the “Got It” problems for those examples.

9. On page 261… Try problems #1-7 on your own.
