Question

After rotating by ${60}^o$ about a centre, a figure looks exactly the same as at its original position. At what other angle will this happen for the figure?

• A. ${120}^o$
• B. ${100}^o$
• C. ${150}^o$
• D. ${90}^o$

Answer 1

Answer: (A)

${120}^o$

So, according to the question, let us assume a figure as circle as refer to IMAGE $01$.

And according to question, above both figures look alike.

So, when we will rotate this figure again by ${120}^o$, this will look like before as refer to IMAGE $02$.
