Question

which angles are complementary to each other? ∠2 and ∠3 ∠1 and ∠3 ∠5 and ∠4 ∠2 and ∠1

Explanation:

Step1: Recall complementary - angle definition

Two angles are complementary if their sum is 90°.

Step2: Analyze the given angles

From the figure, we can see that ∠1 and ∠2 together form a right - angle (as indicated by the right - angle symbol). So, ∠1+∠2 = 90°. Also, ∠2 and ∠3 together form a right - angle, so ∠2+∠3 = 90°.

Answer:

∠2 and ∠3
