Question

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

Explanation:

Step1: Recall definition of supplementary angles

Supplementary angles add up to 180°. When two lines intersect, adjacent - angles formed are supplementary.

Step2: Analyze the given angles

In the figure, ∠3 and ∠4 form a linear - pair (adjacent angles on a straight line). A linear - pair of angles is supplementary.

Answer:

∠3 and ∠4
