  1. Answers to Homework • All answers to SELF TESTS are in the back!!! • Questions???

  2. 4-5 Other Methods of Proving triangles Congruent

  3. Theorem • AAS • Angle-Angle-Side: If two angles and a NON-INCLUDED side are cong., then the triangles are cong. • HL (90) • Hypotenuse-Leg: If the hypotenuse and leg of two RIGHT triangles are cong, then the triangles are cong.

  4. Right Triangles HL: Must have the Hyp and EITHER Leg How do you know which side is the Hypotenuse? It’s across from the 90. Always the longest. Usually the “diagonal”. leg Hypt. leg

  5. TOO: PAGE 142 #10-12 • Name the congruent triangles • Choose from SSS, SAS, ASA, AAS, HL • These Are OVERLAPPING Triangles, watch me do the first one.

  6. #10 ∆ABC and ∆DCB by SSS BC is a shared side Look at the Given info B A E D C

  7. #11 ∆LMN and ∆PNM by ASA P L Q 1 4 2 3 M N

  8. #12 ∆UWY and ∆VZX by HL U V W Z X Y

  9. TOO: same page #1 and 2: There are 2 answers for each! Do these both on your whiteboard. I will pick the best to show to the class!! And you will get a prize!!
