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 trapezium, a kite, an arrowhead, a quadrilateral with 4 different sides. In fact, anything other than a parallelogram (and its special cases).
Equilateral triangles have rotational symmetry.
none shapes have 1 rotational symmetry because in rotational symmetry one is none
A trapezium does not have rotational symmetry.
i am not sure but i think a trapezium has 1 order of rotational symmetry
a trapezium
yes
1
Trapezium
it has 1 order
None.
A kite or an equilateral trapezium.
A kite, An arrowhead, an isosceles trapezium are three possibilities.
