  1. Warm-Up (#33 p.191)

  2. 4.3 Triangle Congruence by ASA and AAS

  3. Learning Target I can show two triangles are congruent using AAS or ASA

  4. Vocabulary Angle Side Angle (ASA): If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

  5. ASA Example PMO ≅ NMO

  6. Vocabulary Angle Angle Side (AAS): If two angles and a non included side are congruent to two angles and the corresponding non included side, then the triangles are congruent.

  7. AAS Example WVY ≅ ZVY

  8. Practice On your 4-3 worksheet, lets do problems 1-9

  9. Practice On your 4-3 worksheet, lets do problems 12-14

  10. Practice Together Proofs – #10 and #11 on your 4-3 worksheet together

  11. Recap Questions • Do you know what AAS and ASA mean? • Do you know how to prove two triangles congruent using AAS or ASA? • Do you remember SAS and SSS? • Can you provide reasoning in a proof? CHALLENGE: Can you write a proof?

  12. Homework p. 197 – 198 #1-18 all • HEADS UP: There will be a quiz this Thursday on 4.1 – 4.3
