Question

which angle is complementary to \angle 2?

Explanation:

Step1: Recall the definition of complementary angles

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

Step2: Analyze the given diagram

From the diagram, we can see that \(\angle3 = 90^{\circ}\). Also, \(\angle1+\angle2+\angle3 = 180^{\circ}\) (a straight - line angle). Since \(\angle3 = 90^{\circ}\), then \(\angle1+\angle2=90^{\circ}\)

Answer:

\(\angle1\)
