Answer:
Order of symmetry = 1
Step-by-step 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.
The given shape, when rotated will only have the shape like original shape after one complete rotation so the order of symmetry is one ..
