50*(50 - 3)/2 = 1175 diagonals.
The formula is: 0.5*(n2-3n) where n is the number of sides of the polygon. So: 0.5*(81-27) = 27 diagonals
For an n-sided polygon, the number of diagonals is 1+2+3+....+(n-4)+2(n-3). For a nine-sided polygon, there are 1+2+3+4+5+2(6)=27 diagonals.
It will have 7 sides
56*(56-3)/2 which is 1484
That polygon is called a "triangle". It has no diagonals.
how many diagonals are there iin a polygon of 11 sides
There are 90 diagonals in a 15-sided polygon.
An 11 sided polygon has 44 diagonals.
A four-sided polygon has two diagonals.
There are 170 diagonals
It has 35 diagonals
There are 77 diagonals
A polygon with 14 diagonals will have 7 sides
It has 40 diagonals.Improved Answer:-Using the formula for diagonals of a polygon: 0.5*(442-132) = 902 diagonals
153 diagonals.
A 7 sided polygon has 14 diagonals
