2.  Last 2 classes, we talked about 3 ways we can determine triangle congruence.  CPCTC – All 3 sides and 3 angles of one triangle are congruent with its corresponding triangle  Side-side-side is when all the sides are congruent to another triangle  Side-angle-side is when 2 sides and their included angle are congruent to a corresponding triangle.  Today We are going to talk about ASA and AAS

3.  Angle–Side–Angle (ASA)– If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

7.  Angle-Angle-Side – (AAS) - If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
