more hyperbolic geometry
In this section, we shall look at the poincare disk model of hyperbolic geometry
and consider the points on the boundary of the disk. These are
not
points of the
geometry, but do provide interesting results.
asymptotic points and asymptotic triangles
perpendiculars and common perpendiculars
