Lines l and m are horizontal and are intersected by lines p and q. At the intersection of lines l and p, the uppercase left angle is 130 degrees. At the intersection of lines q and l, the bottom right angle is 130 degrees. At the intersection of lines m and q, the uppercase right angle is 80 degrees. Which lines are parallel? Justify your answer.

Lines p and q are parallel because same side interior angles are congruent.
Lines p and q are parallel because alternate exterior angles are congruent
Lines l and m are parallel because same side interior angles are supplementary
Lines l and m are parallel because alternate interior angles are supplementary.
