rectangle has inversion (180 deg rotation)
hexagon has 60 deg ratation, cyclic group genterated is
60, 120, 180, 240, 300, 360=0
equilateral triangle has 120 deg rotation, cyclic group genterated is
120, 240, 360=0
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.
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.
For example the triskelion (the three legs) on the Isle of Man flag.
