Classifying Quadrilaterals
The aim of this lesson is to identify different types of quadrilaterals and understand the similarities and differences between them.[br][br][b]1.[/b] Watch this video that has a song about different types of quadrilaterals:

The picture below contains a typical example of what each different type of quadrilateral may look like:
Here is a diagram that shows a hierarchy we can use to classify quadrilaterals:
Here is another diagram that groups quadrilaterals based on the properties that they have in common:

[b]2.[/b] Classify quadrilaterals A to T by colouring. [br](Click a quadrilateral from the right hand column, then click those quadrilaterals A to T in the same class.)[br][br]Drag the ruler and rotate it (using the red point) to measure lengths and right angles.
[b]3.[/b] Examine each of the following quadrilaterals. Determine what type of quadrilateral the figure represents. Justify your conclusions.
