Yes, the capital letter N has rotational symmetry but no lines of symmetry:
None - it has rotational symmetry - not reflection symmetry.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
Depending on the font, they are N, S and Z.
letter o and x
Rotational symmetry is based on points of rotation not lines
M w h
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.
Not necessarily, except rotational symmetry of order 1.
