H I O
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.
Assuming "rotational symmetry" means looks identical when rotated 180 degrees. H I N O S X Z
They are H, I, N, O, S, X and Z.
H, I, N, O, S, X, Z
There are seven: B, H, I, O, S, X, Z
H, I, O, and X have rotational symmetry.
7 have rot
What is the angle of rotation of alphabet S
Assuming "rotational symmetry" means looks identical when rotated 180 degrees. H I N O S X Z
They are H, I, N, O, S, X and Z.
H, I, N, O, S, X, Z
H i n o s x z
No. The only uppercase letters with rotational symmetry are H I N O S X Z Lowercase are l o s x z (and t depending on how it's drawn)
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
There are seven: B, H, I, O, S, X, Z
