No a Z doesn't have a rotational symmetry
z
It has rotational symmetry.
The letters S, N, Z, for example.
Nothing. (Except if you count z axis and you get into 3D!)
No a Z doesn't have a rotational symmetry
The letters H and Z have both line symmetry and rotational symmetry
I, H, N, O, S, X & Z all have rotational symmetry.
Order 2.
Yes is a rotational symmetry 180 degree it will look like these
z
It has rotational symmetry.
A nonrectangular parallelogram has rotational symmetry, but not line symmetry. Additionally, shapes such as the letters S, N, and Z can be rotated to show rotational symmetry, although they do not have line symmetry.
It has a line of rotational symmetry - along the diagonal.
The letters S, N, Z, for example.
Nothing. (Except if you count z axis and you get into 3D!)
Depending on the font, they are N, S and Z.
