Question

Can a triangle have two obtuse angles? Give reason for your answer.

✓

Answer

An angle whose measure is more than $90^{\circ}$ but less than $180^{\circ}$ is called an obtuse angle. A triangle cannot have two obtuse angles because the sum of all the angles of it cannot be more than $180^{\circ}$. It is always equal to $180^{\circ}$.
