Justifications:
1. Vertical angles are congruent (definition of vertical angles)
2. Angle addition postulate (if two angles are congruent to the same angle, then they are congruent to each other)
3. Transitive property (if two angles are congruent to the same angle and one of them is congruent to another angle, then the other two angles are congruent)
4. Corresponding angles congruence postulate (if two lines are parallel, then corresponding angles are congruent)
