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.

Questions:[br][br]1) What does the term "same-side" mean in the phrases "same-side interior angles" and "same-side exterior angles"? [br]Same side interior angles means angles on the same side of the transversal. [br]2) What does the term "alternate" mean in the phrases "alternate interior angles" and "alternate exterior angles"? [br]Alternate interior angles are angles on the opposite side of the transversal.[br]3) Which of the four displayed angles would be considered "interior" angles? Why is this?[br]4) Which of the four displayed angles would be considered "exterior" angles? Why is this?[br]5) How would you describe, in your own words, what it means for a pair of angles to be described as "corresponding angles"?
