Question

Angle greater than ${90}^{\circ }$ is known as obtuse angle.

• A. True
• B. False

Answer 1

The correct option is B False

Given statement, angle greater than ${90}^{\circ }$ is known as obtuse angle is false because only angles that are greater than ${90}^{\circ }$ but less than ${180}^{\circ }$ are known as obtuse angle.
For example: ${210}^{\circ }$ is greater than ${90}^{\circ }$ but it's not an obute angle because it is not less than ${180}^{\circ }$.

Therefore, all angles that are greater ${90}^{\circ }$ cannot be obtuse angle.
