1. TODAY IN GEOMETRY…  Go over proofs from HW #5  4.4 WS Warm Up  Learning Goal: 4.5 You will use postulates Angle-Side-Angle and Angle-Angle-Side to prove triangles are congruent  Independent practice

2. STATEMENT REASON 1. Given 2. Definition of bisector 3. Reflexive Property 4. SAS HOMEWORK #5: PG. 243, #35

3. STATEMENT REASON 1. Given 2. Definition of right triangle 3. Reflexive Property 4. HL HOMEWORK #5: PG. 243, #37

4. WARM UP: (15 minutes)15 minutes 4.4 WORKSHEET We will review solutions as a class

5. So far we have learned the following congruence postulates: SSS SASHL Only for right triangles NEXT… ASA and AAS

6. ANGLE-SIDE-ANGLE (ASA):If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the triangles are congruent. S A A

7. ANGLE-ANGLE-SIDE (AAS): If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent. A A S

8. Identify the proper postulate from the following pictures to prove triangles are congruent. SSS SAS HL ASA AAS

9. ASA S A A

10. SAS A S S

11. SSS S S S

12. AAS A S A

13. STATEMENT REASON 1. Given 2. Reflexive Property 3. AAS

14.
