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.
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.
Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry
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.
A nonagon, which is a polygon with nine sides, can have multiple pairs of parallel lines depending on how it is drawn. However, in a regular nonagon, no sides are parallel because all sides are of equal length and the angles are equal. In general, the number of parallel lines in any polygon depends on its specific arrangement and shape. Therefore, a nonagon can have zero or more pairs of parallel lines, but typically a regular nonagon has none.
To calculate the measure of a central angle of a regular nine-sided polygon, divide 360 degrees by the number of sides. In this case, divide 360 by 9. The measure of the central angle of a regular nine-sided polygon is 40 degrees.

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 has nine lines of symmetry.
Nine. From each vertex to the middle of the opposite side.

A regular octadecagon (an eighteen sided polygon) would have nine diagonals.
Hexagon
a nonagon.
In general, none, but there can be nine.
