It has only 1.
Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
none shapes have 1 rotational symmetry because in rotational symmetry one is none
Order 1. That is, no rotational symmetry.
Rotational symmetry of order 1.
It has 1 order of rotational symmetry.
Not necessarily, except rotational symmetry of order 1.
i am not sure but i think a trapezium has 1 order of rotational symmetry
If the leaf stem is present, it has symmetry of order 1. Otherwise, it can have rotational symmetry of order 3.
Rotational symmetry 2 1 as it is then the second when it is turned half way of a full turn.
The letter U has rotational symmetry of order 1 because it looks the same after a 180-degree rotation.
