how many diagonals are there iin a polygon of 11 sides
For a polygon with n sides, there would be n*(n-3)/2
That polygon is called a "triangle". It has no diagonals.
It depends if the polygon is convex or concave but if it is a regular polygon it would have 560
A polygon with 14 diagonals will have 7 sides
pentagon

A 7 sided polygon has 14 diagonals
There are 77 diagonals
38 diagonals
An heptagon has 7 sides and 14 diagonals
It will have ten sides
A polygon with 14 diagonals will have 7 sides
Let the number of sides be x and by solving the equation for diagonals 0.5(x*x-3x) = 135 the solution is -15 or 18 and so therefore it has 18 sides irrespective if it is an irregular or a regular polygon
