Rectangles and Squares

Just very quickly, to clarify:

  • A rectangle is any two-dimensional shape with four right-angled corners.
  • A square is a rectangle in which all four sides are the same length.
  • Therefore all squares are rectangles, but not all rectangles are squares.

I hope that clears things up.

One thought on “Rectangles and Squares

  1. In addition, we can see rectangles as a sub-family of the parallelograms (quadrilaterals with two pairs of parallel sides).
    Another sub-family are the lozenges, parallelograms in which the diagonals are perpendicular.
    Those examples are a good introduction to categories and sub-categories, some of them overlapping others, partially or totally. A key concept in science.
