Question

which angles are complementary to each other? ∠2 and ∠5 ∠3 and ∠4 ∠3 and ∠2 ∠5 and ∠3

Explanation:

Step1: Recall complementary angles definition

Complementary angles add up to 90°.

Step2: Analyze angle - pairs

From the figure, we see that ∠1 is a right - angle. ∠2 and ∠5 together form ∠1. So, ∠2+∠5 = 90°.

Answer:

∠2 and ∠5
