# Parallel Lines & Related Angles Activity

In this activity, you will explore the different angle relationships formed by parallel lines cut by a transversal.
In the applet below, the dashed brown line is a transversal that intersects

*2 parallel lines*. Take a few minutes to explore the special relationships among the various types of angle pairs formed when a transversal intersects**PARALLEL LINES,**by following the steps below:**STEPS:****1. DRAG the green points around to change the red and/or blue angle measures that appear.**2.**BE SURE TO CLICK ON EACH BOX TO DETERMINE EACH RELATIONSHIP. MAKE NOTE OF EACH RELATIONSHIP.**Use your observations to complete the statements below. Be sure to check your answer
