This document discusses properties of parallel lines and how to determine congruent and specific angles. It states that angles 1, 4, 5, and 8 are congruent at 47 degrees each since they are vertical, corresponding, or alternate exterior angles of parallel lines. It also notes that angle 2 is 133 degrees since it is supplementary to angle 1.

1. What do we know from these parallel lines?

2. Can you determine which angles are congruent? Angles 1, 4, 5, & 8 are congruent Angles 2, 3, 6, & 7 are congruent

3. Can you determine the measure of specific angles with given information? If angle 1 is 47 degrees find the following Angle 4 Angle 5 Angle 2 Angle 8

5. Angle 5 is 47 degrees – corresponding angles

6. Angle 2 is 133 degrees – supplementary angles

7. Angle 8 is 47 degrees – alternate exterior angles or vertical to 5
