Question

which angles are complementary to each other? ∠4 and ∠5 ∠5 and ∠3 ∠6 and ∠3 ∠2 and ∠5

Explanation:

Step1: Recall complementary - angles definition

Two angles are complementary if their sum is 90°.

Step2: Analyze the given angles

In the figure, since the vertical - angle pairs and the right - angle formed are considered. We know that if two angles add up to 90°, they are complementary.
We observe that ∠2 and ∠5 form a right - angle. So, ∠2+∠5 = 90°.

Answer:

∠2 and ∠5
