A letter I i.
There are 11 letters with only one line of symmetry.
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, h, i,
A line has only 1 line of symmetry that i know of.
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, h, i,
A line has only 1 line of symmetry that i know of.
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
a isosceles triangle has at least 1 line of symmetry but only has 9 letters
H i s x z
The answer depends on the font but, c, l, o, v, w, x and z.
Right triangles can have only one line of symmetry. Only right triangles with two 45 degree angles can have a line of symmetry.
a semi-circle only has one line of symmetry
