If it's a regular 9 sided nonagon it's capable of 9 lines of symmetry or mirror images
A 9 sided nonagon normally has no perpendicular lines that meet at right angles
their are 9 lines of symmetry.do you have a boyfriend.
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.
Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry
On a quick estimate, I would think 18, 9 for each interior side and another 9 for each interior angle. * * * * * A nonagon has only 9 lines so the above answer is nonsense. With 9 lines you can have at most 4 pairs of parallel lines (and one not parallel to any). Or you could have a concave nonagon with 1 pair, 1 triplet and 1 quartet of parallel lines, or some other combination.
a nonagon have 9 sides...
A nonagon has 9 sides.
Because nonagon means 9 sides
A nonagon has 9 sides and 9 angles.
A nonagon is a polygon with 9 sides
In a regular nonagon no two sides are parallel.
A nonagon is a plane area enclosed by nine straight lines.
