Quadrilateral property quiz
This activity gives students the opportunity to use concrete and dynamic representations of the shapes. Using dynamic software, students can morph them into different versions of the same shape. They can see, for example, that the diagonals of a rhombus are always perpendicular. They may also realise that it is possible to morph a trapezium, for example, into a parallelogram, then a rectangle, then a square.
At the completion of this activity, students will have a discovered a list of properties for each of the six special quadrilaterals. The final page of the quiz enables students to summarise all their findings in a table that can be retained for future use.
You might also find the Interactive Quadrilaterals page on the Maths is Fun website useful. Please note that the US 'trapezoid' is equivalent to Australia's 'trapezium'.
