A polygon that has 209 diagonals will have 22 sides and it's perfectly acceptable to call it a 22-agon.
There are 90 diagonals in a 15-sided polygon.
It has 40 diagonals.Improved Answer:-Using the formula for diagonals of a polygon: 0.5*(442-132) = 902 diagonals
It is: 0.5*(n2-3n) = diagonals whereas n is the number of sides of the polygon
A polygon with n sides has n*(n - 3)/2 diagonals. So n = 23 gives 23*20/10 = 230 diagonals
209
A polygon that has 209 diagonals will have 22 sides and it's perfectly acceptable to call it a 22-agon.
There is no such polygon that has 95 diagonals because a 15 sided polygon has 90 diagonals and a 16 sided polygon has 104 diagonals.
A polygon that has 104 diagonals will have 16 sides
That polygon is called a "triangle". It has no diagonals.
There are 90 diagonals in a 15-sided polygon.
An 11 sided polygon has 44 diagonals.
A four-sided polygon has two diagonals.
No
a convex polygon
how many diagonals are there iin a polygon of 11 sides
The five sided Polygon has 5 diagonals
