Question

Identify which of the following pairs of angles are complementary and which are supplementary

$45°,45°$

Answer 1

Two angles are said to be supplement if their sum is $180°$

Two angles are said to be complement if their sum is $90°$

Given angles are $45°,45°$

Their sum is $45°+45°=90°$

Since, their sum is $90°$.

Hence, the give pair $45°,45°$ is complementary
