    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 equal (given) |dw:1370499511276:dw|

    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
