1 Benchmark 21 I can identify congruency theorems, SSS, SAS, ASA, AAS, and HL in diagrams

2 Side-Side-Side Postulate If three sides of a Δ are  to three sides of another Δ, then the Δ’s are . A B C X YZ If AB  XY, BC  YZ, AC  XZ, then ΔABC  ΔXYZ

3 Side-Angle-Side Postulate If two sides and the included angle of a Δ are  to two sides and the included angle of another Δ, then the Δ’s are . If AB  XY, BC  YZ, and

4 Angle-Side-Angle Postulate If 2 <‘s and the included side of a Δ are  to 2 <‘s and the included side of another Δ, then the Δ’s are . A BC X YZ If

5 Angle-Angle-Side Theorem If 2 <‘s and a non-included side of a Δ are  to 2 <‘s and a non-included side of another Δ, then the Δ’s are . If

6 Hypotenuse-Leg Theorem If hypotenuse and a leg of a Δ are  to the hypotenuse and a leg of another Δ, then the Δ’s are . If AC  XZ, and BC  YZ then ΔABC  ΔXYZ A B C X Y Z

7 What method is used to prove the triangles are congruent? SSSSAS AASASA

8 What method is used to prove the triangles are congruent? SASAAS SAS

9 What method is used to prove the triangles are congruent? SASAAS HLSAS
