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.
A circle and square.
You turn it a quarter to see if it still has a line of symmetry.
Many figures. For example, an ellipse.
A figure has rotational symmetry if you can turn it about a figure.
z has no line of symmetry and it does have rotational symmetry so yes
It has line symmetry (straight down the center) but not rotational symmetry.
A sphere has rotational symmetry of an infinite degree.
A line has rotational symmetry of order 2.
