7 have rot
As with the Roman alphabet, which you may be familiar with it (since you are using it to read this answer), different letters have different symmetries.
3D shapes don't have lines of symmetry they have plane's of symmetry.
Not many. Depending on how you write, the letters L, O, Q, and X can have diagonal lines of symmetry.
Since a hexagon is a horizontal plane figure it cannot have a horizontal plane of symmetry.

A figure has rotational symmetry when it can rotate onto itself in less than a full rotation.
H,I,O,X Note that if you draw "O" as a perfect circle, it will have infinitely many lines of symmetry.

Four. F, G, J, L
There are seven: B, H, I, O, S, X, Z
Answer: 11, they are A,H,I,M,O,T,U,V,W,X,Y
H, I and X. O has infinitely many and so does have 2.
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
