Exploring plane hyperbolic geometry

Hyperbolic geometry is a geometry whose Euclidean representations cannot be conveniently handled. Straight edge and compass are not the best tools for exploring hyperbolic geometry. Interactive software, as described in this paper, is much more appropriate. A good way of finding cut about a new mathematical structure is on one hand, to visualize tile mathematical objects involved and on tile other; to observe how structure preserving mappings work on these objects. Both of these are supported by our software.
