# 3.1. Naming Angle Positions

Definition: A transversal is a line that intersects 2 other lines at 2 distinct points. [br][br]In the applet, the dashed line below is a transversal. (Actually, each of the three lines displayed below is a transversal.)[br][br]When a transversal intersects 2 other lines, special names are given to certain pairs of angles. [br]These angle pairs are called [b]corresponding angles, alternate interior angles, alternate exterior angles, same-side interior angles, and same-side exterior angles[/b]. [br][br]Explore these angle pairs within the applet below. Then, answer the questions that follow.

What does the term "alternate" mean in the phrases "alternate interior angles" and "alternate exterior angles"? [br][br]3. Which of the four displayed angles would be considered "interior" angles? Why is this?[br][br]4. Which of the four displayed angles would be considered "exterior" angles? Why is this?[br][br]5.
