Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry
A polygon with nine lines of symmetry is a regular nonagon, which is a nine-sided polygon. In a regular nonagon, each vertex can be reflected over a line that passes through the center and a vertex, as well as lines that bisect the angles between the vertices. This symmetry results in a total of nine lines of symmetry.
A regular nonagon, which is a polygon with nine sides, has nine lines of symmetry. Each line of symmetry passes through one vertex and the midpoint of the opposite side, or through the midpoints of two opposite sides. This symmetry reflects the equal length and angles of a regular nonagon.
What is a nonagram? A nine pointed star, perhaps. In any case, a general nonagram, like a general (ie non regular) polygram(!) has NO lines of symmetry.
Has nine sides
A nonagonal prism is a geometric polyhedron whose top and bottom are nonagons (polygons with nine sides) connected to each other by nine rectangles.
In general, none, but there can be nine.

Nine. From each vertex to the middle of the opposite side.
There are 20.5 + 6 + 9 = 20 (Neither circles nor unclosed linear shapes are polygons.)
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.
nonagon(also called an enneagon)

no, only single digit numbers are 8,3,1, and 0
Yes. You can draw infinitely many straight lines from each point.
It is called a nonagon and/or an enneagon. They belong to the greater family of polygons.
