Question

Can two acute angles form a pair of supplementary angles? Give reason in support of your answer.

Sum

Solution

Acute angles are those angles which are less than 90°. If we add two angles which are less than 90°, we get the result less than 180°, e.g. If we add 60° and 70°, we get 60° + 70° = 130° < 180°. Hence, two acute angles cannot form a pair of supplementary angles.
