Question

Which polygon has most number of diagonals

Answer 1

The number of diagonals in a polygon= n(n-3)/2, where n is the number ofpolygon sides. For a convex n-sidedpolygon, there are n vertices, and from each vertex you can draw n-3diagonals, so the total number of diagonals that can be drawn is n(n-3).

So most diagonal is for most sided polygon
