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
