What are the letters in the English alphabet that has reflection symmetry and what has rotation symmetry and which has reflection and rotation symmetry

Capital letters that have rotational symmetry are: Z, S, H, N and O. The letters Z, S, H and N, when rotated 180 degrees clockwise or counterclockwise, will look the same after rotation completion.

Hope it helps you my dear :)

A, H, M, O T, U, V, W, X, Y:
reflection symmetry about a vertical line
at the center

B, C. D,E. H,I, O. X:
reflection symmetry about horizontal
mirror at the center

Rotation symmetry: O (as well as reflection
symmetry)

If S, Z, I, H, X, N are rotated by 180 deg.
about particular axes, they remain same.
