You connect the points that it has, corner to corner and count them. Moo
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
12*(12-3)/2 = 54
octagon
35 diagonals
There are 54 diagonals in a 12 sided shape
it's a 12 sided shape and it has 54 diagonals :D
There are: 0.5*(10002-3000) = 498,500 diagonals

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.)
To find the number of diagonals in a polygon with ( n ) sides, you can use the formula: (\frac{n(n-3)}{2}). For a 152-sided shape, the calculation would be (\frac{152(152-3)}{2} = \frac{152 \times 149}{2} = 11376). Therefore, a 152-sided shape has 11,376 diagonals.
Depends on the shape.
