The answer below is seriously incorrect. In icosahedron is a polyhedron which is a 3-dimensional object. A polygon is a 2-dimensional object and the 20-sided version is called an icosagon.
A polygon with 1,000 sides is known as a chiliagon. A hectogon is a polygon that has 100 sides, and a polygon with 8 sides is called an octagon.
a polygon with 12 sides is called a.. dodecagon
There is no such figure as a 20 degrees polygon.
There is no such polygon but if you meant exterior angles of 20 degrees then it will have 360/20 = 18 sides
heptagon
A icosahedron.
A polygon with 20 sides is an icosagon.
A polygon with 1,000 sides is known as a chiliagon. A hectogon is a polygon that has 100 sides, and a polygon with 8 sides is called an octagon.
a polygon with 12 sides is called a.. dodecagon
A polygon with 12 sides is called a dodecagon.
A polygon with 5 sides is called a pentagon.
It has 360/20 = 18 sides
A regular polygon
an Irregular Polygon
the 11th sides of polygon is called UNDECAGON....... the 12th sides is DODECAGON.....
A polygon with 27 sides would be called an icosakaiheptagon.
There is no such figure as a 20 degrees polygon.
