How would you prove that ∠2 congruent ∠4?

From concept of base angle of parallel line, Option(D) Corresponding angles are congruent.
Given that ∠1 ≅ ∠2 .
In the diagram given aside, line a and b are parallel where the ∠4 and ∠2 are base angle subtended by the parallel lines.
From the traversal property of congruency, we know that the base angles of a parallel lines always subtend equal and congruent angles when it is intercepted by a common traversal.
Thus, from concept of base angle of parallel line, Option(D) Corresponding angles are congruent.
