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.

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.
