1. 4.4 Proving Triangles are Congruent by ASA and AAS
Definite ASA and AAS

2. Angle-Side-Angle (ASA)
If two angles and a side between them are congruent in two different triangles, then the triangles are congruent.
Since

3. Angle-Angle-Side
If two angles and a side not between them are congruent in two different triangles, then the triangles are congruent.
Since

4. Are The Triangles congruent?
