Step-by-step explanation:

According to the graph, givens are

Now, and are vertical angles, because they are in opposite sides of C, and they don't have any side in common. By congruence postulates, we know that

So, at this point, we have three elements congruent:

This allow us to use ASA postulate, that is, Angle-Side-Angle postulate, because we have congruence between corresponding angles and the side in between.

In addition, the ASA postulate states that if two triangles have two corresponding angles congruent, and the sides between them are also congruent, then those triangles are congruent.

Therefore, the right answer is ASA.
