AV and H only
BD1 and D2 only
CV, H, D1, and D2
DNo labeled lines
Solution & Explanation:The four identical tabs are placed evenly on a square, so vertical, horizontal, and diagonal folds all make matching halves.

Which added mark would keep all 4 lines of symmetry of a plain square tile?
AOne dot exactly at the center
