摘要：The quasi-hyperbolic plane is one of nine projective-metric planes where the absolute figure is the ordered triple { j_1, j_2, F}, consisting of a pair of real lines j_1 and j_2 through the real point F. In this paper some basic geometric notions of the quasi-hyperbolic plane are introduced. Also the classification of qh-conics in the quasi-hyperbolic plane with respect to their position to the absolute figure is given. The notions concerning the qh-conic are introduced and some selected constructions for qh-conics are presented.
