We used Geogebra to allow the students to create geometrical functions, and see the links between geometry and algebra.

One activity used this starting point in Geogebra:


and asked the students to plot all the points that were equidistant from the line and the point.  It is set up so that the students create y=x^2.

The students had a lesson on spherical geometry - showing them that the angles in a triangle do not always add up to 180, and a lecture on reflectional symmetry in euclidean geometry, spherical geometry and hyperbolic geometry.
