Question

∠4 and ∠5 are complements, and ∠1 and ∠5 are complements
by the congruent complements theorem, which angle is congruent to ∠4?
○ ∠1
○ ∠2
○ ∠3
○ ∠5

Explanation:

The Congruent Complements Theorem states that if two angles are complementary to the same angle, then they are congruent. Here, ∠4 and ∠1 are both complementary to ∠5.

Answer:

∠1
