Maybe I'll do a video.So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length. 12 comments.A quadrilateral is a mathematical name for a four-sided polygon.
