a hexagon ( triangle has 3 and a hexagon has 6)
hexagon
octagon-8 sides
An heptagon has 7 sides and 14 diagonals
A regular hexagon
In a polygon with n sides, we have n(n-3)/2 diagonals. In a convex polygon with n sides, you can draw n-3 diagonals from each vertex, but you are counting each one twice you so you need to divide by do. That is why we have n(n-3) divided by 2

A hexagon and a triangle.
A 7 sided polygon has 14 diagonals

the polygon would be a square
Thirteen separte hexagons have 13x6 sides, or 78 sides. However, it's possible that they have shared borders, so then there would be fewer because you wouldn't count the same side twice if it was shared.
sum of exterior angles in a polygon is always equal to 3600,sum of all the interior angles is given by (n-2)1800, where n is the number of sides of the polygon.According to the question,(n-2)1800=2(3600)n-2=4so n=6answer:6
