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"? [color=#980000]The "same sided" phrases mean that the angles are in the same side of the transversal dotted line.[/color][br]2) What does the term "alternate" mean in the phrases "alternate interior angles" and "alternate exterior angles"? [color=#980000]The "alternate" mean that the angles are in the opposite side the transversal dotted line.[/color][br]3) Which of the four displayed angles would be considered "interior" angles? Why is this?[color=#980000] The angles that are displayed that are "interior" is the same sided interior angles because they are in the inside of the triangle.[/color][br]4) Which of the four displayed angles would be considered "exterior" angles? Why is this? [color=#980000]The exterior angles are considered the same sided exterior angles because they are outside the angle.[/color][br]5) How would you describe, in your own words, what it means for a pair of angles to be described as "corresponding angles"? [color=#980000]The corresponding angles are angles that are across from each other.[/color]
