Which of the following statements is true? 1) the triangles are congruent by the asa congruence postulate. 2) the triangles are congruent by the sas congruence postulate 3) the triangles are congruent by the sss congruence postulate 4) the triangles are congruent by the aas congruence theorem

choice 2) SAS

AB = DE is one pair of congruent sides that forms the first S in SAS. The other S in SAS refers to the pair of congruent sides BC = EF. The A in SAS is the angle pair angle B = angle E. Note how angle B and angle E are between the two pairs of congruent sides. The order of the letters matters because SAS is different from SSA, which is not a valid congruence argument. Check out the attached image.

The information provided is SIDE, included ANGLE, and SIDE

2) SAS
