it's a 12 sided shape and it has 54 diagonals :D
12=)Improved Answer:-It has 14 because the formula of 0.5*(49-27) = 14 diagonals
Just calling it a "1000-sided shape" is fine. It is too much trouble to search for fancy name for figures with many sides.
A 3-sided polygon is a triangle. There is no diagonal for that shape since all non-adjacent vertices share a line segment!
There are 35 diagonals in a 10 sided decagon
35 diagonals
There are 54 diagonals in a 12 sided shape

it's a 12 sided shape and it has 54 diagonals :D
1/2*(1002-300) = 4850 diagonals
There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
Number of diagonals = 18*(18-3)/2 = 135
It has 27 diagonals

I am sure that a shape with six side has 9 diagonals. (I found out cause I really wanted to help people.)
12*(12-3)/2 = 54
