Any regular polygon of n sides, has an order of symmetry of n. Therefore, since a nonagon has nine sides, a nonagon has an order of symmetry of 9.
A nonagon has 9 rotation symmetry
four
The number of lines of symmetry in a polygon corresponds to the number of sides it has. If a polygon has n sides, then its symmetry will be n lines of symmetry and it will have one point of symmetry. A pentagon has five lines of symmetry, nonagon has 9, n-gon has n lines of symmetry, so on and so forth.
The letters H and Z have both line symmetry and rotational symmetry
nonagon
Has nine sides
A line of symmetry must go from one vertex to the midpoint of the opposite side.
Any regular polygon of n sides, has an order of symmetry of n. Therefore, since a nonagon has nine sides, a nonagon has an order of symmetry of 9.
A regular nonagon with 9 sides has a rotational symmetry of 9.
A nonagon has 9 rotation symmetry

It need not have any. It can have 9.
In general, none, but there can be nine.
Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry
If it's a regular 9 sided nonagon it's capable of 9 lines of symmetry or mirror images
