Question

find the order of rotational symmetry in this shape.

Explanation:

Step1: Recall the formula for rotational symmetry

The order of rotational symmetry of a shape is the number of times it fits onto itself during a full rotation of \(360^{\circ}\).

Step2: Analyze the equilateral triangle

For an equilateral triangle, when rotated by \(120^{\circ}\) (\(\frac{360^{\circ}}{3}\)), it maps onto itself. So in a \(360^{\circ}\) rotation, it will fit onto itself \(3\) times.

Answer:

\(3\)
