Question

Manasa says, "Each angle in any pair of complementary angles is always acute". Do you agree? Give reason.

Answer 1

We know that, if two angles are complementary, then their sum is ${90}^o$.

$\therefore$ For a pair of angles to be complementary, both of them should be less than $90°$.

Also we know, angles less than $90°$ are called acute angles.

Hence, Manasa is right, i.e., each angle in any pair of complementary angles is always acute.
