the letters are : E
Four. F, G, J, L
H, I, O, X. Of course, it may depend on the font.
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.
H, I and X. O has infinitely many and so does have 2.
letter o and x
Vertical lines of symmetry: A, H, I, M, O, T, U, V, W, X, Y Horizontal lines of symmetry: B, C, D, E, H, I, K, O, X Other: O
I x o l
Three capital letters that have two lines of symmetry are "O", "H", and "I" since they can be reflected either horizontally or vertically and still look the same.
H,I,O,X Note that if you draw "O" as a perfect circle, it will have infinitely many lines of symmetry.
