Question

In the diagram, AB is perpendicular to BC. Name:

a. two supplementary angles
b. two complementary angles

Answer 1

a. ∠3 and ∠4

b. ∠1 and ∠2

Explanation:

Since AB is perpendicular to BC, there's a 90° angle where the letter B is. Therefore, ∠1 and ∠2 are both complementary angles because the sum of both angles add up to 90°

∠3 and ∠4 are both supplementary because they add up to 180° (which is a straight line)
