Given: Segment CE bisects <BCD; <A is congruent to <B
Prove: Segment CE ll to segment AB
-I used the exterior angle theorem to set the four angles equal to each other, but i don't know how to move on from there. The converse of something (maybe alternate interior angle) is important in proving it parallel also.
No idea where angle A or angle B is. Thought B was a point.
