There are 11 letters with only one line of symmetry.
A B C D E H I K M O T U V W X Y the letters above all have a line of symmetry
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
There is only one capital letter: O.
A letter I i.
A, B, C, D, E, M, T, U, V, W, Y, and Z.
Only the I has a horizontal line of symmetry. Visualize folding PIZZA in half through the letters. Only the I would fold down perfectly on top of itself, so it has a horizontal line of symmetry.
a isosceles triangle has at least 1 line of symmetry but only has 9 letters
The letter - H
Only vertical: A, M, T, U, V, W, Y Only horizontal: B, C, D, E, K Both vertical and horizontal: H, I, O, X
