I think it's <3 and <2 because they are alternate exterior angles

anonymous · Answer

<I and <4 make more sense, because these angles from lines a, b.

anonymous · Answer

If you make <5 and <6 congruent then the rest would be congruent as well.

anonymous · Answer

I don't get it it would be <5 and <6 because they are vertical angles or mine which are alternate interior angles
