Yes, a smiley face does have rotational symmetry. Rotational symmetry means that an object looks the same after a certain degree of rotation. In the case of a smiley face, if you rotate it 180 degrees, it will still look the same. This is because the eyes, nose, and mouth are symmetrically arranged around the center of the face.
Line symmetry.
one
It has rotational symmetry to the order of 2
A regular nonagon with 9 sides has a rotational symmetry of 9.
Rotational symmetry of order 1.
Line symmetry.
A smiley face has no rotational symmetry. So the order is 1.
yes it could still be rotatonal symmetry
