Is there an infinite sided shape?

In geometry, an apeirogon (from the Greek words “ἄπειρος” apeiros: “infinite, boundless”, and “γωνία” gonia: “angle”) or infinite polygon is a generalized polygon with a countably infinite number of sides. Apeirogons are the two-dimensional case of infinite polytopes.

Does a circle have infinite sides?

It might be more defensible to say that a circle has infinitely many corners than infinitely many sides (although this is not a question that seems to get asked very often). … Every point on the boundary of the circle is an extreme point, so it is certainly true that a circle has infinitely many.
