  • That would be a property of a rhombus not a square, which is covered by the facts;
    1. kite has adjacent sides =
    2. parallelogram has opposite sides =
    3. rhombus has all the properties of a kite and a parallelogram
    thus rhombus has all four sides =

  2. 2. The Quadrilateral FamilyQuadrilaterals can be classified according to the features they possess.QuadrilateralKiteTrapeziumParallelogramRhombus RectangleSquare
  3. 3. The Quadrilateral FamilyQuadrilaterals can be classified according to the features they possess.As you branch down the quadrilateral family, the quadrilaterals becomemore specialised in their features.QuadrilateralKiteTrapeziumParallelogramRhombus RectangleSquare
  4. 4. The Quadrilateral FamilyQuadrilaterals can be classified according to the features they possess.As you branch down the quadrilateral family, the quadrilaterals becomemore specialised in their features.Any property that you know about the quadrilaterals a particular shapehas branched from can be used for that quadrilateral as well as thespecific properties for that shape.QuadrilateralKiteTrapeziumParallelogramRhombus RectangleSquare
