Question

which angle is complementary to ∠1? ∠4 ∠3 ∠2 ∠5

Explanation:

Step1: Recall the definition of complementary angles

Complementary angles are two angles whose sum is \(90^{\circ}\).

Step2: Analyze the given angles

From the figure, \(\angle1+\angle5 = 90^{\circ}\) (since the right - angle is formed by \(\angle1\) and \(\angle5\) together).

Answer:

\(\angle5\)
