    for similarity, it is sufficient if you can just prove two Angles are congruent. third angle becomes congruent by triangle sum property anyways.

    these two angles are congruent (vertical angles theorem) |dw:1370499555685:dw|

    you have 2 sets of congruent angles, so you can use the AA (angle angle) similarity theorem to prove the two triangles are similar
