An apeirogon is a 2-dimensional polygon with a countably infinite number of edges. It can be thought of as a tiling of a one-dimensional line by line segments. In the hyperbolic plane, regular apeirogons are circumscribed by a horocycle, their lines of symmetry converging to a point at infinity. More general apeirogons include the apeirograms ( for natural ), failed star polygons ( for irrational real ), and pseudogons ( for nonzero imaginary ).

Its Bowers acronym is aze.
