If you wish to communicate information, I suggest you call it an 2000-gon. Although there is a prefix for 2000 (dikilo-) I suggest you keep it simple. Not only is the use of long Greek prefices pretentious, you will only annoy the reader who will probably have to consult a dictionary. Having said that, if you do want to be pretentious or obfuscate, you can use the link below for polygons with up to 999 sides. http://faculty.kutztown.edu/schaeffe/Tutorials/General/Polygons.html
A 2000-sided shape is called a 2000-gon. The suffix "-gon" is used to denote a polygon with a specific number of sides, so a 2000-sided shape would be referred to as a 2000-gon. The term "gon" comes from the Greek word "gonia," meaning angle, and is commonly used in geometry to describe polygons with varying numbers of sides.
An 11 sided shape is an Eptogon
A nine sided shape or polygon is called a nonagon.
Why not just call it "a 130-sided shape"? because its not called that, spaz.
A five sided geometric shape is called a pentagon.
