Use the given figure to complete the statement below. ∠2 and ∠4 are angles.  supplementary adjacent vertical  complementary 

Easy, its vertical :3

∠2 and ∠4 are vertical angles.

Explanation: We are given two linear lines that intersect each other and forms angles.

Theorem: When two lines intersect, the vertical angle are congruent to each other which means that the two angles are equal. Vertical angles are the angles that are opposite to each other.

In the given figure, ∠2 and ∠4 are opposite to each other, hence they are considered as vertical angles.

∠2 = ∠4 (From above theorem)
