  • Definitions evolve from common properties of classes of shapes.
  • \r\n\t
  • Definitions are needed in order to have a shared understanding of classes of shapes, and be able to reason together about these shape classes.
  • \r\n\t
  • We evolve shared (working) definitions of squares, rectangles, parallelograms and rhombuses to use in class. For example: A square could be defined as a quadrilateral with all sides equal and all angles as right angles. A rhombus could be defined as a quadrilateral with all sides equal.
