It depends on the font. But l, o, s, x, z, H, I, N, O, S, X and Z.
no
it means that if you are looking at a shape of a triangle then will it be able to go upside down looking the same way? well no it wont the point was on top not on the bottum right?

H, I, O, and X have rotational symmetry.
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.

I, H, N, O, S, X & Z all have rotational symmetry.
The letters in the English alphabet that have rotational symmetry are H, I, O, S, X, and Z. This means that these letters look the same when rotated 180 degrees. Other letters may have reflective symmetry but do not maintain their appearance when rotated.
Bilaterally
Rotational symmetry in the alphabet refers to how certain letters look the same when rotated around a central point. For example, the letters O, S, and H exhibit rotational symmetry at 180 degrees, appearing unchanged when flipped upside down. Other letters, like A and M, can also display symmetry, but typically at different angles. Overall, not all letters possess rotational symmetry, and those that do vary in their symmetry properties.
The letters H and Z have both line symmetry and rotational symmetry
