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.
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.
