Question

The diagram shows the outline of a 50 cent coin from Fiji.
What is its order of rotational symmetry?

• A. 8
• B. 9
• C. 12
• D. 15

Answer 1

The correct option is C 12

A line of symmetry is a line that divides a figure into two corresponding parts, each of which is the mirror image of the other.

All the diagonal $6$ which passes through the center of the figure are line of symmetry of the given Coin.

Also the $6$ longest lines which cut the side of the given Coin are also the lines of symmetry of given coin.

Hence given figure have $12$ lines of symmetry .
