Copia de Saccheri Quadrilateral Construction

• With points A and B create a hyperbolic line on the Poincare circle. • With the Hyperbolic Perpendicular Bisector tool, along with points A and B, construct the perpendicular bisector of segment AB at Q. • Using the Hyperbolic Perpendicular at Point tool create h-lines perpendicular to AB at pts A and B. • Define another point P on the perpendicular bisector of AB. • Again using Hyperbolic Perpendicular at Point tool, create a line perpendicular to PQ at P
