Question

Which one of the following angles is reflex ?

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is B B

An angle which is greater than ${180}^{\circ }$ and less than ${360}^{\circ }$ is called a reflex angle.
In the given figure, A is less than ${90}^{\circ }$, C is equal to ${90}^{\circ }$, D is greater than ${90}^{\circ }$ and less than ${180}^{\circ }$ and B is greater than ${180}^{\circ }$ and less than ${360}^{\circ }.$ Hence, B is the only reflex angle.
