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 is a nine-sided polygon. In a nonagon, there are four pairs of parallel lines. This is because the nonagon can be divided into three sets of parallel lines, each containing three parallel lines. Each set of parallel lines consists of three pairs of parallel lines.
a nonagon have 9 sides...
A nonagon has 9 sides.
Because nonagon means 9 sides
A nonagon is a plane area enclosed by nine straight lines.
In a regular nonagon no two sides are parallel.
A nonagon has 9 sides and 9 angles.
