Its construction is degenerate in a Euclidean plane because either the two sides would coincide or one or both would have to be curved; however, it can be easily visualised in elliptic space.

In geometry, a chiliagon (/ˈk?li?g?n/) or 1000-gon is a polygon with 1,000 sides. Philosophers commonly refer to chiliagons to illustrate ideas about the nature and workings of thought, meaning, and mental representation.

## What is a shape with 10000 sides called?

In geometry, a myriagon or 10000-gon is a polygon with 10,000 sides. Several philosophers have used the regular myriagon to illustrate issues regarding thought.

## What is the polygon rule?

Polygons. A ‘polygon‘ is the mathematical term used to describe a two-dimensional (2D) closed shape with straight sides. If all of the angles of a 2D shape are equal and all the sides are equal, then it is regular polygon. If the angles are not equal and the sides are not equal, then the shape is an irregular polygon.
