Question

What is the order of the rotational symmetry of the given figure about the point marked ‘x’?

• A. $0$
• B. $1$
• C. $2$
• D. $3$

Answer 1

The correct option is C $2$

In a complete turn of ${360}^{\circ }$, the number of times an object looks exactly the same is called the order of rotational symmetry.

Mark the top corner as A and rotate it into ${180}^{\circ }$.

The figure will look like


Again turn it into ${180}^{\circ }$.

The figure will look like



Thus the figure looks same at the angles ${180}^{\circ },{360}^{\circ }$ so the order of symmetry of the given figure is 2.
