Question

At $9$ o'clock, the angle formed between the hands of a clock (in clockwise direction) is a:

• A. Complete angle
• B. Reflex angle
• C. Zero angle
• D. None of the above

Answer 1

The correct option is B Reflex angle

We know, angles more than ${180}^o$ and less than ${360}^o$ are called reflex angles.

Thus at $9$ o'clock, the angle formed between the hands of a clock is a reflex angle, i.e. more than ${180}^o$ but less than ${360}^o$.

Hence, option $B$ is correct.
