Question

Name the angle ${91}^0$ as acute or obtuse or straight or reflex or right angle.

Answer 1

We know that an angle whose measure is greater than ${90}^0$ degree and less than ${180}^0$ degree is called an obtuse angle.

Here, ${91}^0$ is greater than ${90}^0$ and lees than ${180}^0$.

Hence, ${91}^0$ is an obtuse angle.
