A nonagonal prism has nine faces. It has a total of 18 vertices. A nonagonal prism also has 27 edges.
14 diagonals
14
It is: 0.5*(10 squared - (3*10)) = 35 diagonals
A 7 sided septagon or heptagon has 14 diagonals
A nonagonal prism has nine faces. It has a total of 18 vertices. A nonagonal prism also has 27 edges.
It has 0 volume diagonals and 6 face diagonals hence the total number of diagonals are 6
Well, honey, a hexagonal prism has six sides, so it has six diagonals on the top face and six on the bottom face, making a total of 12 diagonals there. Then you've got the diagonals connecting the corresponding vertices on the top and bottom faces, which adds another 12 diagonals. So, in total, a hexagonal prism has 24 diagonals. Hope that clears things up for you, darling!
There are two diagonals in a trapezoid.
It has 20 diagonals
14 diagonals
Total diagonals formula: 0.5*(n^2 -3n) whereas n is the number of sides of the polygon
None
14
It is: 0.5*(10 squared - (3*10)) = 35 diagonals
A 7 sided septagon or heptagon has 14 diagonals
The formula is: 0.5*(n2-3n) = diagonals whereas n is the number of sides of the polygon
