User Manual for the Interactive Geometry Software Cinderella

Jürgen Richter-Geberts ist Leiter des Lehrstuhls Geometrie und Visualisierung am Zentrum Mathematik der TU München. Er ist Initiator der Mathematikausstellung "ix-quadrat" und des Web Portals "Mathe-Vital".

Cinderella is a unique, technically very sophisticated teachware for geometry. It will be used as a tool by students learning Euclidean, projective, spherical and hyperbolic geometry, as well as in geometric research by scientists. Moreover, it can also serve as an authors' tool to design web pages with interactive constructions or even complete geometry exercises.
