Parallel Lines & Related Angles Activity
In this activity, you will explore the different angle relationships formed by parallel lines cut by a transversal.[br][br]In the applet below, the[color=#d69210] dashed brown line[/color] is a [color=#d69210]transversal[/color] that intersects [i]2 parallel lines[/i]. [br][br]Take a few minutes to explore the special relationships among the various types of angle pairs formed when a transversal intersects [b]PARALLEL LINES, [/b]by following the steps below:[br][br][b]STEPS:[br][/b][br][b]1. DRAG the [color=#0a971e]green points[/color] around to change the [color=#c51414]red[/color] and/or [color=#1551b5]blue[/color] angle measures that appear.[br][br][br][/b]2. [b]BE SURE TO CLICK ON EACH BOX TO DETERMINE EACH RELATIONSHIP. MAKE NOTE OF EACH RELATIONSHIP.[/b]
Use your observations to complete the statements below. Be sure to check your answer[br][br]

When a transversal intersects PARALLEL LINES, all pairs of alternate interior angles are
When a transversal intersects PARALLEL LINES, all pairs of alternate exterior angles are
When a transversal intersects PARALLEL LINES, all pairs of same side interior angles are
When a transversal intersects PARALLEL LINES, all pairs of same side exterior angles are
