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 9 sided nonagon normally has no perpendicular lines that meet at right angles
How many parallel lines does a trangle have?
A triangle can have no parallel lines.
How many pairs of parallel lines does a pentagon have?
A pentagon has no parallel lines.
How many parallel lines is there in a cube?

How many parrellel lines are there in a nonagon?
In a regular nonagon no two sides are parallel.
How many pairs of parallel lines does a nonagon have?
up to four pairs is the answer
Is a nonagon parallel or concruent?
Well a nonagon is a nine sided polygon. If you make the lines or sides parallel, then you will have a parallel figure. Or some parallel lines on a figure (polygon). If you choose to make your polygon (nonagon) have a pair of congruent sides, then your polygon will have some congruent sides. Therefore it really matters what your shape looks like. For example, a quadrilateral can be a square or a kite (or many others but I'm just using these) a kite might have no parallel lines and a square may have 2 sets of parallel lines. Do you get it? Does that answer your question? FYI: A nonagon is also known as a enneagon :)
How many parallel sides are on a nonagon?
There are no parallel sides on a nonagon (nine-sided figure)... Regular shapes with an odd-number of sides have no parallel sides.
How many perpendicular lines are on a nonagon?
A 9 sided nonagon normally has no perpendicular lines that meet at right angles
How many diagonal lines does a nonagon have?
A nine sided nonagon has 27 diagonals
Does a nonagon have perdicular or parallel diagonal?
parallel
How many parallel sides does a nonagon have?
A nonagon can have none, or anything up to four pairs of parallel sides. You can even have two quartets of parallel sides in you allow concave nonagons.
How many parallel pairs of sides can a nonagon have?
Up to four.
How many lines of symmetry in a nonagon?
In general, none, but there can be nine.
How many parallel lines does a trangle have?
A triangle can have no parallel lines.
How many pairs of parallel lines does a parallelgram have?
it has too parallel lines!
