3lines are shown. a line with points p, r, n intersects a line with points o, r, m at point r. a line extends from point r to point l in between angle m r p.
marcus states that angle orp and angle lrp are a linear pair. which best describes his statement?

he is correct. the angles share a common vertex so they are a linear pair.
he is correct. the angles share a common ray so they are a linear pair.
he is incorrect. angle orp does not form a linear pair with another angle in the diagram.
he is incorrect. ray ro and ray rl are not opposite rays.
