    Two choices show triangles congruent, and two choices show triangles similar. You are given info about angles of triangles being congruent. There is no info at all about congruent sides. Can you prove two triangles congruent without knowing anything about congruent side lengths?

    No, it's not C.

    To prove triangles congruent we use: ASA, AAS, SAS, SSS, HL, HA Every one of those methods involves at least one pair of congruent sides. We don't know any sides to be congruent here, so no answer here can have congruent triangles. Choice C has congruent triangles.

    Eliminate choices B and C because they involve congruent triangles which cannot be proved without at least one pair of congruent angles.

    Now look at choice A. Does it make any sense to say m<3 = m<6? Angles 3 and 6 are not congruent that we know of.
