20.
153 diagonals.
infiniteImproved Answer:-The formula is: 0.5*(n2-3n) where n is the number of sides of the polygonSo: 0.5*(144-36) = 54 diagonals

Draw a nine sided polygon.
A person can draw a five-sided polygon by drawing a pentagon. This is the figure that looks like a house.
It depends if the polygon is convex or concave but if it is a regular polygon it would have 560
n-3 diagonals. Of the n vertices of the polygon, you cannot draw diagonals to the two adjacent vertices since these are sides of the polygon and so not diagonals. And you cannot draw a diagonal from a vertex to itself. So those are three vertices that are ruled out, leaving n-3.
