Question

which postulate would prove these two triangles are congruent? sss sas neither

Explanation:

1. First, identify the given congruent parts: The diagram shows two sides with congruence marks (so two pairs of equal sides) and the included angle (vertical angles, which are equal) between them.
2. Recall the SAS (Side - Angle - Side) postulate: 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.
3. The SSS (Side - Side - Side) postulate requires three pairs of congruent sides, but here we have two sides and the included angle, so SAS applies.

Answer:

B. SAS
