In the definition of regular polygon at the Wikipedia, there is this statement about the limit of a n-gon:
"In the limit, a sequence of regular polygons with an increasing number of sides becomes a circle, if the perimeter is fixed, or a regular apeirogon, if the edge length is fixed."
My question is:
I am trying to understand how to imagine an apeirogon versus a circle, but that definition (regarding edge length) and the visual representation found in the Wikipedia or Wolfram is not very clear to me.
Indeed looking for information in other websites, I found also something called "infinigon", but it seems that there is not formal definition (or I did not find it).
This topic could be very basic but I did not find former questions at MSE, and I am interested in understand the difference. Thank you!
