A lower-case 'h' has rotational symmetry. An upper-case 'H' also has reflective symmetry.
Two.
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
The letters: I O H X o x all exhibit bilateral symmetry and rotational symmetry, with O and X exhibiting it in both upper and lower case.
The letter H has a rotational symmetry of order 2, meaning it looks the same after a 180-degree rotation.
Both.
Only H.
A lower-case 'h' has rotational symmetry. An upper-case 'H' also has reflective symmetry.
Two.
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
The letters H and Z have both line symmetry and rotational symmetry
H, I, O, and X have rotational symmetry.
It is 2.
The letters: I O H X o x all exhibit bilateral symmetry and rotational symmetry, with O and X exhibiting it in both upper and lower case.
The letter U has rotational symmetry of order 1 because it looks the same after a 180-degree rotation.
