i am not sure but i think a trapezium has 1 order of rotational symmetry
A kite, An arrowhead, an isosceles trapezium are three possibilities.
Trapezium
An isosceles trapezium (or isosceles trapezoid) has an order of rotational symmetry of 1. This means it can only be rotated 360 degrees to look the same at one position, as it does not map onto itself at any other angle of rotation. In contrast, shapes with higher rotational symmetry can appear the same at multiple angles.
A kite or an equilateral trapezium.

it has 1 order
A trapezium does not have rotational symmetry.

yes
Trapezium
None.
For example the triskelion (the three legs) on the Isle of Man flag.

A Parallelogram, a Diamond and a rhombus all have rotational symetry of two. Others Kite 1 Trapezium 1 Square 4
A line has rotational symmetry of order 2.
