Yes. Draw the letter H on a piece of paper and turn it upside down. You'll notice that it still looks like an H. It does not have 90 degree (or 270 degree) rotational symmetry, though - if you turn it sideways, it looks like a weird elongated I.
When you rotate it around a point found in the middle of the figure 180 degrees. For example, H does have rotational symmetry however, E doesn't
Assuming "rotational symmetry" means looks identical when rotated 180 degrees. H I N O S X Z
H
A lower-case 'h' has rotational symmetry. An upper-case 'H' also has reflective symmetry.
Yes, it does.
H, I, N, O, S, X, and Z.

H, I, N, S, X and Z. I make that 6, not 3! And O has 180 degree symmetry and more!
The letters H and Z have both line symmetry and rotational symmetry
Linear (horizontal as well as vertical), plus rotational (180 deg).
H, I, O, and X have rotational symmetry.
It has rotational symmetry of order 2.
It is 2.
