What is "apeirogon"

n. (context mathematics geometry English) A polygon having an infinite number of sides and vertex.

In geometry, an apeirogon is a generalized polygon with a countably infinite number of sides. It can be considered as the limit of an n-sided polygon as n approaches infinity. The interior of a linear apeirogon can be defined by a direction order of vertices, and defining half the plane as the interior.

This article describes an apeirogon in its linear form as a tessellation or partition of a line.
