In a regular polygon, the formula to calculate the number of diagonals is n(n-3)/2, where n is the number of sides. For a 27-gon, there would be 27(27-3)/2 = 351 diagonals. These diagonals are line segments that connect non-adjacent vertices of the polygon.

A regular 12 sided dodecagon has 54 diagonals.
54
It has 9 diagonals whether or not if its a regular or an irregular hexagon
5 diagonals
8 diagonals
27 diagonals

There are 9 diagonals in any hexagon!The hexagon does not have to be regular.
A regular 12 sided dodecagon has 54 diagonals.
There are 21 of them.
54
It has 20 diagonals and is made up by 6 triangles
O.5*(49-21) = 14 diagonals
It has 9 diagonals whether or not if its a regular or an irregular hexagon
0.5*(862-258) = 3569 diagonals
