Unit 3- Day 3- Parallel Lines & Related Angles

Author:afeldman, Tim Brzezinski
Topic:Angles
Recall that a transversal is a line that intersects 2 other lines at 2 distinct points. 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 pair formed when a transversal intersects PARALLEL LINES. As you do, be sure to drag the green points around to change the red and/or blue angle measures that appear.
