Question

Which of the list of letters that all have line symmetry A, B, C, D, S, T, U, V, L, M, N, O, P, W, X, Y, Z

Answer 1

Assuming uppercase letters in a typical geometric (sans‑serif/block) font, these from your list have at least one line of (reflection) symmetry:

- A — vertical
- B — horizontal
- C — horizontal
- D — horizontal
- T — vertical
- U — vertical
- V — vertical
- M — vertical
- O — many axes (vertical, horizontal, diagonal — any line through the center)
- W — vertical
- X — vertical, horizontal and diagonal axes (multiple)
- Y — vertical

Those without any line symmetry (though some have 180° rotational symmetry) are:
- S, L, N, P, Z

Note: symmetry can depend on typeface (e.g., some fonts make B or D slightly unequal top/bottom), so the answer above uses the idealized/common block letter shapes.
