A rigid shape is when you cant push/pull on it and make it turn into a different shape. You can make shapes rigid by adding "braces", which are lines that you put inside the shape to make triangles (which are rigid). For instance, a square is notrigid. To make it rigid, you would put a brace inside diagonally. This would create TWO triangles, and therefore, rigid. ~xDragonx
35 diagonals
There are 54 diagonals in a 12 sided shape
A nanogon has no diagonals because there is no such shape. A nonagon, on the other hand, has 9*(9-3)/2 = 27 diagonals.
I am sure that a shape with six side has 9 diagonals. (I found out cause I really wanted to help people.)

There are 54 diagonals in a 12 sided shape
There are: 0.5*(10002-3000) = 498,500 diagonals
it's a 12 sided shape and it has 54 diagonals :D
There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
1/2*(1002-300) = 4850 diagonals

Number of diagonals = 18*(18-3)/2 = 135
