The pairs of angles on opposite sides of the transversal but outside the two lines are called Alternate Exterior Angles.

The only answer choice I'd think it would be is something that's not on the answer choice listings. :/

C is wrong answer..

gabbyalicorn · Answer

Hmm. That's strange... Is there any tips or strategies to find 2 and 12 faster? (just curious) Or like, is there a different way.

Also, thanks for your help.
