Question

What is the order of rotational symmetry of the above pattern?

• A. 6
• B. 9
• C. 12
• D. 18

Answer 1

The correct option is B 9

If a figure is rotated by ${40}^o$ i.e, $({\frac{1}{9}}^{th}$ of ${360}^o)$ ,then it exactly fits its own outline.

Therefore given figure has rotational symmetry of order $9$.
