A pair of parallel lines is shown cut by a transversal. Angle p is located in the upper right exterior next to the transversal, and angle q is located in the bottom left exterior corner of the transversal.
Which of the following best represents the relationship between angles p and q? (4 points)

p = 180 degrees − q

q = 180 degrees − p

p = 2q

p = q
