- 1
When parallel lines are cut by a transversal, the corresponding angles are congruent.
- 2
Angles that are linear pairs are supplementary, meaning that they have a sum of 180 degrees.
- 3
Using the X's and O's mindset, all angles labeled with an X are congruent to each other, and all angles labeled with an O are congruent to each other.
