We can choose three pairs from either of the two planes as long as they are from the same plane each time. _____3.a line segment has two endpoints. True B. Line m is perpendicular to line p since the two lines intersect to make right angles. The two angles are alternate interior angles as well. If they intersect, give the point of intersection. Below are four terms that describe different ways coplanar lines may interact: Parallel lines, segments, or rays: Lines that run in the same direction and never cross (like two railroad tracks) are called parallel.
