Parallel and Perpendicular Lines
For the purposes of this exercise, it's important to remember that the lines that are displayed represent lines, not line segments. While line segments have end points, lines continue infinitely in both directions, so if they are not parallel, they will intersect at some point. Some of the diagrams will contain lines that are not parallel, yet will not have a point of intersection on the diagram; for these diagrams, you must determine visually whether or not the lines will intersect at a right angle.
