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.

    Someone knows more calculus than they are letting on...

    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.

    Not if this square is a projection of a curved surface

    If it is a projection, then there are more than two curved sides, which also begs credence to the interpretability of the angles they intersect.

    Well angles between 3 points are always going to be angles. If your choose a different configuration of dimensional parameters you can effectively project a square from the 2D plane into this exact shape, then logically the angles would follow.

    Hey, that's my job!

    Also I don't think that's technically the technical classification. I think that sidedness is an attribute that simply doesnt apply to curves.
    You can approximate curves with some number of sides, and the approximation gets more accurate as the number approaches infinity, but it doesn't actually have the infinite sides.

    Very cool! I'm always happy to learn something new!

    I mean, I'm just pedantic; double check with a mathematician, to be sure lol

    I'm genuinely curious, what is your job that requires arithmetic?
