Both.
A lower-case 'h' has rotational symmetry. An upper-case 'H' also has reflective symmetry.
The letter H has a rotational symmetry of order 2, meaning it looks the same after a 180-degree rotation.
Yes, it does.
M w h
Only H.
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.
The letter H has an order of rotational symmetry of 2. This means that if you rotate the letter 180 degrees, it looks the same as it did in its original position. Additionally, it has symmetry about a vertical axis, so it can also be reflected and still appear unchanged.
H
The letters H and Z have both line symmetry and rotational symmetry
H, I, O, and X have rotational symmetry.
It is 2.
