decagon
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.

What is a shape with 1 billion sides called?
A gigagon is a two-dimensional polygon with one billion sides. It has the Schläfli symbol. (using Bowers’ arrays). To an unaided observer, a gigagon resembles a circle.
What is a 20 sided polygon called?
Icosagon
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.
How many sides does a ten sided polygon have?
As long as a two dimensional shape features ten sides and is fully enclosed a shape can be accurately referred to as a 10 sided polygon or a irregular decagon. Like a regular decagon a irregular decagon will also have 10 equal congruent vertices and angles.
What do you call a 10 sided shape?
A flat 10-sided shape with sides of equal length is called a decagon. A solid 10-sided shape with faces of equal size and shape is called a decahedron. Two-dimensional shapes are called polygons, which means they are flat, straight-sided and closed.
What do you call a 60 sided polygon?
A 60 sided polygon is called a hexacontagon. A 100 sided polygon is called a hectagon. A 6 sided polygon is called a hexagon. A 666-gon. Not all polygons have a special name. You could translate 666 into Greek and glue “gon” onto the end but nobody outside of Greece would know what you were talking about so there wouldn’t be any point.
Is there such thing as a 10 sided decagon?
No, while most decagons which you’ll come across will probably be regular decagons, irregular decagons also exist. As long as a two dimensional shape features ten sides and is fully enclosed a shape can be accurately referred to as a 10 sided polygon or a irregular decagon.
