O'Reilly Media - Tech Books, DRM-Free Ebooks, Videos This book uses, at its core, a couple of services to permit the reader to do code experiments using pre-written Python modules in a specially packaged format. The idea is that you install the two services required and then you can experiment to your heart's content with the code. The Problem C.a.R. - News Compass and Ruler - Construct and Rule C.a.R. simulates constructions with a pair of compasses and a ruler on a computer. By moving basic points, students can experience changes in the construction, check the construction for correctness. Moreover, tracks of points or polar sets of lines can be generated to establish new conjectures and gain geometrical insights.
