Consider the figure where line segment MN is parallel to line segment PQ M P 1 4 2 3 5 N Q Which statement must be true Since m 1 m 2 m 3 180 m 1 m 4 and m 3 180 m 1 m 4 and m 3 m25 we can prove tha m 4 m 2 m 5 180 Since m 1 m 2 m 3 180 m 1 m 5 and m 3 m 4 we can prove that m 5 m 2 m 4 180 Since m 1 m 2 m 3 360 m 1 m 4 and m 3 m 5 we can prove that m 4 m 2 m 5 360 Since m 1 m 2 m 3 360 m 1 m 5 and m 3 m 4 we can prove that m 5 m 2 m 4 360
