8 sides
Triangle has 3 sides Quadrilateral has 4 sides Pentagon has 5 sides Hexagon has 6 sides Heptagon has 7 sides Octagon has 8 sides Nonagon has 9 sides Decagon has 10 Undecagon has 11 sides Dodecagon has 12 sides And there are many more because polygon means many sides
12 - 9 = 3.
12 - 9 = 3
One more side.
8 sides
I think it is 4! :} * * * * * You think wrong! A dodecagon has 12 sides, a pentagon has 5. So a dodecagon has 7 more sides.
4 more sides
It has: 12-3 = 9 more sides
Six
2
9
A decagon has 10 sides, and a quadrilateral has 4 sides, therefore a decagon has 6 more sides than a quadrilateral.
An octagon has 8 sides and a quadrilateral has 4 sides.An octagon has 8 - 4 = 4 more sides than a quadrilateral.
4 more sides
A hexagon has 6 sides, and a quadrilateral has 4 sides. Thus, a hexagon has 2 more sides than a quadrilateral does.
