Answer:

1.Yes,  vertical angles prove lines parallel if there is a transversal and the corresponding vertical angles are congruent

2. x= 12

Answer:

1. In order to use Theorem 10.7, you need to show that corresponding angles are congruent. You can use the fact that ∠1 and ∠2 are vertical angles, so they are congruent. Because ∠2 and ∠3 are corresponding angles, if you can show that they are congruent, then you will be able to conclude that your lines are parallel.
