Are the two triangles similar? How do you know?
for similarity, it is sufficient if you can just prove two Angles are congruent. third angle becomes congruent by triangle sum property anyways.
@Emily778 you familiar wid vertical angles ?
good :) see of u can use it here, at the intersection M.
can you tell me the answer? (: Preettyy pleeeaassee :D
Answer : they are similar, by AA similarity. what use knowing an answer without knowing how ? :)
I have over 50 questions. Cheating on one question won't hurt..
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
