14. E.
15. m∠7 + m∠2 = 180

Answer 1

1 and 8 are alternate exterior angles, so if those are equal,, we can conclude the lines are parallel and that 6 and 3, the other alternate exterior angles are equal. We can conclude 5 and 4 are equal because they are alternate interior angles. We cannot conclude 3 and 8 are equal. We cannot conclude 7 and 2 are supplementary because they are not consecutive interior angles.
