H, I, N, O, S, X and Z. Each of order 2.
In some fonts the X may have order 4 and the O may have infinite order.
The order of rotational symmetry in alphabets varies depending on the specific letter and the alphabet in question. For instance, in the English alphabet, letters like O and X have infinite rotational symmetry, while others like A and B have lower orders (1 or 2) depending on how they can be rotated and still appear unchanged. Generally, most letters in the Latin alphabet have a rotational symmetry order of 1 or 0, as they do not appear identical after a 180-degree rotation. Other alphabets, such as Greek or Cyrillic, exhibit similar variations in rotational symmetry among their letters.
Infinite.
A, B, C, D, E, F, G, J, K, L, M, P, Q, R, T, U, V, W, Y. A figure has rotational symmetry of order 1 only if it has to be rotated through 360 degrees before its image is congruent. In common usage, it has NO rotational symmetry.
A line has rotational symmetry of order 2.
Z S H and N
yes, it has a rotational symmetry of 180 degrees, and of course 360. like if you flipped it upside down, then put it on top of the other one it would look the same. just not a lowercase.
Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
It has rotational symmetry to the order of 2
If it is a regular octagon then it has rotational symmetry to the order of 8
It does have rotational symmetry of order three.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
A parallelogram has rotational symmetry of order 2.
