Rotational symmetry refers to symmetry of the figure when it is rotated about a single point in the same plane. Lines of symmetry apply to reflections. You do not have lines of rotational symmetry.
Yes, the capital letter N has rotational symmetry but no lines of symmetry:
A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflective symmetries (six lines of symmetry).

A parallelogram has no lines of symmetry, but it has rotational symmetry.

I believe that it is 0, 1 or 6 lines of symmetry and rotational symmetries of order 1, 2, 3 or 6
A sphere has one point of symmetry (at its very center) if one considers rotational symmetry in its three dimensions. If one is only considering reflectional symmetry, it would have an infinite number of lines of symmetry.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
