Answer:
B. ∠1 ≅ ∠2; alternate interior angles theorem
Explanation:
In the figure attached, the complete problem is shown.
As can be seen in the figure, ∠1 and ∠2 are interior angles.
The lines dividing the parking spaces are parallel
The Alternate Interior Angles theorem states: if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent
