In the good old days (when I was at school and was taught about rotational symmetry) it had one, but the modern definition is to say it has none.
No a Z doesn't have a rotational symmetry
A trapezoid has no rotational symmetry.
It has line symmetry (straight down the center) but not rotational symmetry.
It does have rotational symmetry of order three.

Equilateral triangles have rotational symmetry.
It has rotational symmetry to the order of 2
