1. 6-1 Lines Mr. Cline Course 3 Mathematics Laveen Campus

2. Objective: I can ID relationships of angles formed by two parallel lines cut by a transversal.

3. Essential Question: How are the measures of angles related when parallel lines are cut by a transversal?

4. Transversal Angles

7. Example 1:

8. Example 2:

9. Got it? A

10. Finding Missing Angle Measures: When two parallel lines are cut by a transversal, special angle relationships exits. If you know the measure of one of the angles, you can find the measures of all of the angles. Suppose that ___________. You can use that to find the measures of angles 2, 3, and 4.
