      a square is a POLYGON with four equal sides and four right angles.

      a polygon is a closed shape with only straight lines.

      I’m pretty sure “parallel” could be in there too, but these rules would make that redundant.

        But the picture doesn’t say anything like that. It just says it “has four right angles” and is obviously tongue-in-cheek
