Interactive Geometry with Cinderella

The primary and most fundamental usage of Cinderella still is interactive geometry, often also called dynamic geometry. With a few mouse clicks you can generate constructions from elementary geometry, projective geometry or even hyperbolic geometry and fractals. The main feature of Cinderella is the so called move mode, sometimes also called drag mode. This mode gives you much more than an ordinary geometric drawing tool. You can drag the base elements of your construction and while you do this all the dependent elements follow accordingly. Using move mode you can explore many geometric constructions and observe effects and theorems on an experimental level.

The following explanations give you a detailed guide through all the different construction tools and possibilities that are available for doing interactive geometry. After a description of the elementary construction modes an explanation of various views and types of geometry is given.

As a novelty, Cinderella.2 lets you access various geometric transformations as geometric objects. Using these transformations it is also possible to generate transformation groups and fractals easily.
