A dodecagon has 12 sides
12 points * * * * * A decagon has 10 vertices (points) and 10 sides. A polygon with 12 is a dodecagon.
a 12 sided polygon!:) * * * * * Oh dear! A 12 sided polygon is a dodecagon, not a decagon. The correct answer is 10 sides.
A decagon has 10 equal sides, so if the perimeter is 120 cm each side must be 12 cm
No... A decagon has 10 sides... A Dodecagon has 12...

3 sides: triangle 4 sides: quadrilateral 5 sides:pentagon 6 sides:hexagon 7 sides: heptagom 8 sides: octagon 9 sides: nonagon 10 sides: decagon 11 sides: unodecagon ? 12 sides: duodecagon 13 sides: trisca-decagon? 14 sides: ( I am tired on making up names- try quator-decagon, or look it up.)
Well, 2-D shape is a square, or a quadrilateral
