3. The Quadrilateral Family
Quadrilaterals can be classified according to the features they possess.
As you branch down the quadrilateral family, the quadrilaterals become
more specialised in their features.

4. The Quadrilateral Family
Quadrilaterals can be classified according to the features they possess.
As you branch down the quadrilateral family, the quadrilaterals become
more specialised in their features.
Any property that you know about the quadrilaterals a particular shape
has branched from can be used for that quadrilateral as well as the
specific properties for that shape.

5. The Quadrilateral Family
Quadrilaterals can be classified according to the features they possess.
As you branch down the quadrilateral family, the quadrilaterals become
more specialised in their features.
Any property that you know about the quadrilaterals a particular shape
has branched from can be used for that quadrilateral as well as the
specific properties for that shape.
e.g. a rhombus has the properties of a rhombus, parallelogram,
trapezium, kite and quadrilateral.
