PyGeo: a Dynamic 3d geometry laboratory

PyGeo is a dynamic geometry laboratory and toolkit. PyGeo may be used to explore the most basic concepts of Euclidean geometry at an introductory level, including by elementary schools students and their teachers. But is particularly suitable for exploring more advanced geometric topics – such as projective geometry and the geometry of complex numbers The intent is to bring a rich visual experience to the study of both synthetic and analytic geometry.
