>>11074917> to try to express it as a limit of a 2 dimensional object doesn't work.A square is also a 1d object, as well as are polygons that are not filled in.
>You would have infinite corners, and corners aren't a property of a 1-dimensional objectLiterally the same thing can be said about the ACTUAL definition of the length of a differentiable curve - you approximate the curve with polygons and take the limit as the number of corners goes to infinity. Also you seem to be fundamentally confused about what infinity is, there's no actual shape at the end of the process in OPs pic, it's just a sequence of shapes. The endshape is undefined, so it doesn't make sense to talk about it. All limits are inherently defined in finitistic terms, which includes the length of an arbitrary curve.
You have no idea what you're talking about and the people who replied to you with "/thread" should be embarrassed.
