Chapter 4 Review page 5 Prove congruent
’s using ASA and AAS
ASA (Angle-Side-Angle) Postulate If two angles and the included side of a triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
In the figure,
.
Therefore, by the ASA postulate,
.
AAS (Angle-Angle-Side) Postulate If two angles and a non-included side of a triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.
In the figure,
Therefore, by the AAS postulate,
