English capital letters, sorted by symmetry:
- Vertical line symmetry: A, H, I, M, O, T, U, V, W, X, Y
- Horizontal line symmetry: B, C, D, E, H, I, K, O, X
- Both vertical and horizontal: H, I, O, X
- Rotational (180°) symmetry: H, I, N, O, S, X, Z
- No symmetry: F, G, J, L, P, Q, R
Example
Word "MOM" written on paper looks the same in a vertical mirror (all letters symmetric + palindrome).
"SWIMS" rotated 180° still reads SWIMS — an ambigram.
"SWIMS" rotated 180° still reads SWIMS — an ambigram.
💡 Tip:Look at each letter and try folding/spinning it mentally.
