Question

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

Explanation:

Step1: Recall complementary - angles definition

Two angles are complementary if their sum is 90 degrees.

Step2: Analyze the given angle - pairs

From the figure, we can see that \(\angle5\) is a right - angle (\(90^{\circ}\)). And \(\angle5=\angle4+\angle3\). So, \(\angle4 + \angle3=90^{\circ}\).

Answer:

\(\angle3\) and \(\angle4\)
