In the figure shown, which pair of angles must be complementary?

∠aoc∠aoc and ∠cod∠cod

∠cob∠cob and ∠aoc∠aoc

∠aoc∠aoc and ∠dob∠dob

∠cod∠cod and ∠dob∠dob

∠COD and ∠DOB are complementary angles

Step-by-step explanation:

To Find: In the figure shown, which pair of angles must be complementary?

1.∠AOC and ∠COD

2.∠COB and ∠AOC

3. ∠AOC and ∠DOB

4.

∠COD and ∠DOB

Complementary angles : Angles whose sum is 90° are called pair of complementary angles

In option 4 ∠COD and ∠DOB

Since referring the figure we can see that

∠COD + ∠DOB =90°

Hence  ∠COD and ∠DOB are complementary angles
