There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
1/2*(1002-300) = 4850 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.)
It has 27 diagonals
Any quadrilateral (4-sided shape) has 2 diagonals.
35 diagonals
No because a nonagon which is a 9 sided shape has 27 diagonals
9 diagonals
There are 54 diagonals in a 12 sided shape
A shape with five diagonals is a hexagon. A hexagon has six sides, and the formula for calculating the number of diagonals in a polygon is given by ( \frac{n(n-3)}{2} ), where ( n ) is the number of sides. For a hexagon, substituting ( n = 6 ) results in ( \frac{6(6-3)}{2} = 9 ) diagonals. Therefore, a shape that specifically has five diagonals is a pentagon, as it fits the formula with ( n = 5 ): ( \frac{5(5-3)}{2} = 5 ).
There is none. A 5 sided shape is a pentagon but that has 10 diagonals, not 2.
