Respuesta :
A.) Lines a and b are parallel because their corresponding angles are congruent.
Answer:
D. Lines e and f are parallel because their same side exterior angles are supplementary.
Step-by-step explanation:
I know for a fact that it is not C or A even though those ones would make the most sense. This leaves B and D; It's not B because is said that angles A and B are both exterior which is incorrect, A in interior and B is Exterior. This leaves us with D as our final answer.
