Finding a part of an angle with two triangles

  1. Mar 13, 2015 #1
    I've never really understood this bit of trig, I think I get it if there are two parallel angles (parallelogram). But, I do not understand how you go about when the triangles aren't in a parallelogram.

    I have no idea what you are talking about! How are these two triangles related? Do you mean two triangles with one side in common, so that they form a quadrilateral with that side as diagonal?

    I agree w/ Halls. Your question is so vague as to be meaningless. Best would be to draw a diagram of the kind of situation that you are trying to understand.

    Well I'm thinking of two related triangles that share a side. You know part of an angle, and maybe one other angle. Could I just use algebra to solve the missing angle bit?

    You need to be more precise.

    Do you find it impossible to draw a diagram? As mathman said, you are STILL not telling us what it is you want to know.
