Question

This star is made up of equilateral triangles: What is the order of rotational symmetry of the star?

• A. 3
• B. 4
• C. 6
• D. 12

Answer 1

The correct option is A 3

If a figure is rotated by ${120}^o$ $({\frac{1}{3}}^{th}$ of ${360}^o)$ ,then it exactly fits its own outline.

Therefore given figure has rotational symmetry of order $3$.
