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.

What is the order of rotational symmetry in all alphabets?

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.
