Can be used to scaffold colleagues' entry into using Cabri Geometry. The general geometry investigations are also applicable to GeoGebra, which is popular free dynamic geometry software.
 * Cabri Geometry movie clips** http://www.chartwellyorke.com/cabriimages/movies/cabrimovies.html

What generalisations can be formed? What attributes are consistent? Explore some boundary cases (eg. Does the generalisation still hold when the line segments don't intersect?)

 * Line segments formed from midpoint of squares formed on opposite sides of any quadrilateral** [[file:Quad-Sq, Mid-point.fig]]

Is there a relationship between the area and perimeter of parallelograms as they diminish in size?
 * Parallelograms formed by intersection of angle bisectors in a parallelogram** [[file:Parallelogram, angle bisect.fig]]
