In geometry, an apeirogon (from the Greek word ἄπειρος apeiros, "infinite, boundless" and γωνία gonia, "angle") or infinite polygon is a generalized polygon with a countably infinite number of sides. Apeirogons are infinite 2-polytopes and can be considered as limits of an n-sided polygon as n approaches infinity.
