1. B E L L W O R K Is there enough given information to prove the triangles congruent? If there is, state the postulate or theorem.

2. 4. Angle-Side-Angle (ASA) *2 angles and the INCLUDED side I f 2 angles & the included side of one ∆ are @ to the 2 angles and included side of another ∆, then the ∆’s are @ . 5. Angle-Angle-Side (AAS or SAA) *2 angles and the NON included side I f 2 angles and the non-included side of one ∆ are @ to the 2 angles and non-included side of another ∆,then the ∆’s are @ . 4.5 Prove Triangles Congruent by ASA & AAS A B C D E F W X Y M N P

4. Other Scenarios 1 . Angle-Angle-Angle (AAA) *** This scenario only proves that 2 triangles are similar. *** No triangle congruency can be determined. 2. Side-Side-Angle (SSA) *** No conclusion can be made from S-S-A
