It has rotational symmetry to the order of 2
Rotational symmetry of order 1.
A regular nonagon with 9 sides has a rotational symmetry of 9.
They have not got any rotational symmetry
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
heck yeah it does * * * * * It can do, but it need not have any non-trivial rotational symmetry. A regular decagon will have rotational symmetry of order 10.
A decagon can have rotational symmetries of order 1, 2, 5 or 10.

A regular decagon has rotational symmetry = 10.For irregular decagons, it could be less (either 2 or none.)
A decagon has 10 sides, so it also has 10 angles. Each angle of a decagon is 36 degrees (360 degrees divided by 10). Therefore, a decagon has 10 angles of rotation symmetry.
A line has rotational symmetry of order 2.
Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
It has rotational symmetry to the order of 2
If it is a regular octagon then it has rotational symmetry to the order of 8
It does have rotational symmetry of order three.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
