## 11 x1 t07 04 quadrilateral family (2012)Presentation Transcript

• The Quadrilateral FamilyQuadrilaterals can be classified according to the features they possess. Quadrilateral Trapezium Kite Parallelogram Rhombus Rectangle Square
• 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. Quadrilateral Trapezium Kite Parallelogram Rhombus Rectangle Square
• 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.
