Read each question carefully and determine if the triangles are congruent. If they are, state the congruence postulate (SSS, SAS, or ASA) that proves their congruence.

1. Which postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent?

SAS

ASA

SSS

AAS

1. If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent by ASA.

True

False

1. The postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

2. When using the SAS postulate, the congruent angle must be the two congruent sides.

For each pair of triangles below, determine if they are congruent. If so, state the congruence postulate (SSS, SAS, or ASA) that justifies your answer.
