None.
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. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
None, normally. One if it is an isosceles trapezium.
It has 1 vertical line of symmetry
None.
A trapezium can have at most 1 line of symmetry.
Rotational symmetry is based on points of rotation not lines
None.
