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, I, O, X. In some fonts the symmetry may not apply.
H, I, N, O, S, X, and Z
Depending on the font, they are N, S and Z.
ALL letters have at least one line of rotational symmetry. However - if you mean reflective symmetry, the letters F, G, J, L, P, Q, R, S, & Z do not.

The answer depends of the font.In broad terms, in the upper case letters:F, G, J, L, P, Q and R.The others have reflective (or line) symmetry, or they have rotational symmetry, or both.
The letters H and Z have both line symmetry and rotational symmetry
H, I, O, and X have rotational symmetry.
H, I, N, O, S, X, and Z
