Answer:
4
Explanation:
First of all we will define rotational symmetry.
Rotational symmetry is when a shape looks the same after some rotation or less than one rotation.
The order of rotational symmetry is how many times it matches the original shape during the rotation.
So for the given shape, we can observe that the shape has four same type of sides. The shape in rotation will be like original shape 4 times in a complete rotation. So the order of symmetry is 4 ..
