A figure has rotational symmetry if you can turn it about a figure.
There are 10 letters in the alphabet that achieve rotational symmetry when displayed in their capital form. These letters: A, H, I, M, O, U, V, W, X, and Y.
H,i,o,x
The letters S, N, Z, for example.
The rotational symmetry of a plane object is the number of times it will look exactly like its original shape when you rotate it through 360 degrees in its plane. A whole alphabet has no rotational symmetry but some letters in an alphabet may have rotational symmetry. The number of symmetries depends on the alphabet, whether the letters are in upper or lower case as well as the font used.
The letters H and Z have both line symmetry and rotational symmetry
H, I, O, and X have 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.
A figure has rotational symmetry if you can turn it about a figure.
I, H, N, O, S, X & Z all have rotational symmetry.
There are 10 letters in the alphabet that achieve rotational symmetry when displayed in their capital form. These letters: A, H, I, M, O, U, V, W, X, and Y.
H,i,o,x

A figure has rotational symmetry when it can rotate onto itself in less than a full rotation.
The letters S, N, Z, for example.
A B C D E H K M U V W X Y * * * * * What? Most of these letters do not have rotational symmetry and so cannot have rotational AND line symmetry. Or did the meaning of AND change last night? The only upper case letters with both are H, I, O, X
