Introduction to Planimetry of Quasi-Elliptic Plane

The quasi-elliptic plane is one of nine projective-metric planes where the metric is induced by the absolute figure FQE ={;j1, j2, F}; consisting of a pair of conjugate imaginary lines j1 and j2, intersecting at the real point F. Some basic geometric notions, definitions, selected constructions and a theorem in the quasi-elliptic plane will be presented.
