Recall that a [color=#d69210]transversal[/color] is a line that intersects 2 other lines at 2 distinct points. [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 pair formed when a transversal intersects [b]PARALLEL LINES[/b]. [br][b]As you do, be sure to 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. [/b]
When a [color=#d69210]transversal[/color] intersects PARALLEL LINES, pairs of [b]corresponding angles[/b] are________________________.
When a [color=#d69210]transversal[/color] intersects PARALLEL LINES, pairs of [b]alternate INTERIOR angles[/b] are ______________________.
When a [color=#d69210]transversal[/color] intersects PARALLEL LINES, pairs of [b]alternate EXTERIOR angles[/b] are ______________________.
When a [color=#d69210]transversal[/color] intersects PARALLEL LINES, pairs of [b]same-side INTERIOR angles [/b]are ______________________.
When a [color=#d69210]transversal[/color] intersects PARALLEL LINES, pairs of [b]same-side EXTERIOR angles[/b] are ______________________.
