Well, It is but not because ... rotation symmetry, and a square has - turn (or 90-degree) rotation symmetry. As you may have already observed, many figures have 180-degree rotation symmetry but no other rotation symmetry. A figure has 180-degree rotation symmetry if it looks the same when turned halfway around ... Soo yeah ... I think I am right, So sorry if I'm wrong.
