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 9 lines of symmetry and rotational symmetry of order 9. However, an irregular nonagon can be asymmetric.
It may, or it may not, be symmetrical. There are different types of nonagons.
nonagon
Because nonagon means 9 sides
Not a regular nonagon.
A nonagon has nine sides.
A nonagon
a nonagon
A nonagon.
"nonagon" is not a prefix.
Nonagon.
A nonagon is a 2D shape so you cannot make a 3D nonagon!
Only if all nine sides are the same length.
