MCQ
After rotating by $60^\circ $ about a centre, a figure looks exactly the same as at its original position. At what other angle will this happen for the figure?
- ✓$120^\circ $
- B$100^\circ $
- C$150^\circ $
- D$90^\circ $
✓
Answer
Correct option: A.
$120^\circ $
It can be observed that if a figure looks symmetrical on rotating by 60°, then it will also look symmetrical on rotating by multiples of $60^\circ .$
i.e., $120∘, 180^\circ , 240^\circ $ and $360^\circ $.
i.e., $120∘, 180^\circ , 240^\circ $ and $360^\circ $.
