I, H, N, O, S, X & Z all have rotational symmetry.
I, O, S, H, Z, X, N just by quickly looking at my keys this is what I got?
A figure has rotational symmetry when it can rotate onto itself in less than a full rotation.
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
Z S H and N
M w h
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.

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.
E s i o
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
