Here are seven quadrilaterals.
Can you name them?
What properties do you associate with each type?
Which quadrilaterals are special cases of which other ones?
Explore these shapes (by moving the vertices).
Why are some vertices green, others red, and still others are not coloured at all?
How might you use this applet in teaching, and to which class/grade?
