Question

which angles are complementary to each other? ∠4 and ∠6 ∠5 and ∠2 ∠5 and ∠4 ∠1 and ∠2

Explanation:

Step1: Recall complementary angles definition

Two angles are complementary if their sum is 90°.

Step2: Analyze given angles

From the figure, we can see that ∠5 and ∠4 together form a right - angle (marked by the right - angle symbol). So, ∠5+∠4 = 90°.

Answer:

∠5 and ∠4
