5.3 SAS Triangle Congruence Essential Question: What does the SAS Triangle Congruence Theorem tell you about triangles?

SAS (Side-Angle-Side) Triangle Congruence Theorem: If 2 sides and the included angle of 1 triangle are congruent to 2 sides and the included angle of another triangle, then the triangles are congruent by SAS.

Are the triangles congruent by SAS? 1. 3. 2.

5. Statements Reasons 1. BD is the perpendicular bisector of AC 2. AD = CD 3. <BDA and <BDC = 90 4. BD = BD 5.

Statements Reasons 1. CD bisects AE and AE bisects CD 2. AB = EB and CB = DB 3. <ABC = <EBD 4. Triangle ABC = Triangle EBD
