Modern software for geometry like Cabri-géomètre [2], GEOLOG [4] or Felix [6] allows a drawing to be varied on the screen by direct manipulation with the mouse. The user can move certain parts of a drawing, and the software maintains all existing geometrical relationships. For instance, Cabri-Géomètre provides this basic feature by its ‘drag mode’: Fig. 1 shows the cursor dragging the vertex of a square. While the vertex is being moved around, the computer continues to draw a square.
