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 X C B Z Y 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 . A B C X Y Z If AB XY, BC YZ, and <B <Y then ΔABC ΔXYZ

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 X C B Z Y If <A <X, <B <Y, AB XY, then ΔABCΔXYZ

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 . A B C X Y Z If <A <X, <B <Y, and BC YZ then ΔABCΔXYZ

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 . A B C X Y Z If AC XZ, and BC YZ then ΔABC ΔXYZ
