    …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.

      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.

        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.
