Answer 1

Answer:

. Given Two lines m and n are parallel and another two lines p and q are respectively perpendicular to m and n. ... We know that, if a transversal intersects two lines such that a pair of interior angles on the same side of the transversal is supplementary, then the two lines are parallel. Hence, p||g.
