Lines e and f are intersected by lines a and b. At the intersection of lines a and e, the uppercase right angle is 110 degrees. At the intersection of lines b and e, the uppercase right angle is 110 degrees. At the intersection of lines b and f, the bottom right angle is 80 degrees.
Which lines are parallel? Justify your answer.

Lines a and b are parallel because their corresponding angles are congruent.
Lines a and b are parallel because their same side exterior angles are congruent.
Lines e and f are parallel because their corresponding angles are congruent.
Lines e and f are parallel because their same side exterior angles are supplementary.

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.
