Oh let's get pedantic!
The curved edges technically have infinite "side".
....and a square has four interior 90 degree angles.
...and based on the infinite number of sides for a curved line aspect, the "90 degree" angles would all be +/- the limit as it approaches zero, so never truly 90 degrees but always an infinite fraction away.
the angles are interior if you go into the scary world of high level maths and their weird fucking geometries.
this is a square, from a certain point of view
Someone knows more calculus than they are letting on...
Hey, I failed the highest level of calculus possible. Twice.
I'll have you know that I passed the two lowest levels of calculus required for my degree. So you know, I'm something of an expert.
Yeah, we gonna need more rigor on this one.
"A square is a shape made up of four equally long lines a, b, c, d where a is perpendicular to c and d and parallel to b. Each of these lines meet exactly two other lines at it's ends."
I'm not a mathematician so there might an odd case somewhere in there. Maybe it has to be confined to a shared plane?
Lines are infinitely long... do you mean line segments?
Wikipedia has a good enough definition: "It has four straight sides of equal length and four equal angles." Nice and simple.
Pentagon fits that definition also since it doesn't specify "it has four and only four" sides
So you're saying this is the outline of a square in the astral plane? Because it sounds like you're saying this is a square in the astral plane.
No, just a 2d plane
