Question 516400
You'll have to explain the question more clearly for a full solution (since we don't know what or where angles 1, 2, and 3 are). Please don't be afraid to try a proof (it is simply like an argument -- you take a position and you defend it, in this case, prove it).


Heads up: "Complementary" is the correct spelling. "Complimentary" refers to giving someone a compliment.
