A 9 sided nonagon is comprised of 7 triangles
There are 11 triangles in an undecagon. The number of sides of a polygon is the number of triangles it has.
There are no parallel sides on a nonagon (nine-sided figure)... Regular shapes with an odd-number of sides have no parallel sides.
Number of triangles in a polygon is determined by (n-2) = number of triangles, whereas n is the number of sides of the polygon
In general you would need to select a vertex of the nonagon and join it to the other vertices (except the two adjacent ones). This will divide the nonangon into 7 triangles. Measure the sides and/or angles of these triangles and calculate their areas. Add these together to get the area of the nonagon.If the nonagon is regular then there are formulae to calculate its area. These depend on whether you know the side length, apothem or circumradius.
There are 9 vertices in a nonagon.
