136 APOLLONIUS OF PERGA as particular cases of the new diameter of reference. The three sections, the parabola, hyperbola, and ellipse are made in the manner shown in the figures. In each case they pass through a straight line DE in the plane of the base which is at right angles to BC, the base of the axial triangle, or to BG produced. The diameter PM is in the case of the
THE CONIGS, BOOK I 137 parabola parallel to AG \ in the case of the hyperbola it meets the other half of the double cone in P' ; and in the case of the ellipse it meets the cone itself again in P f . We draw, in the cases of the hyperbola and ellipse, AF parallel to PM to meet BG or BG produced in F. Apollonius expresses the properties of the three curves by means of a certain straight line PL drawn at right angles to PM in the plane of the section. In the case of the parabola, PL is taken such that PL:PA = BG 2 : BA . AC; and in the case of the hyperbola and ellipse such that PL:PP'=BF.FC:AF 2 . In the latter two cases we join P'L, and then draw VR parallel to PL to meet P'L, produced if necessary, in R. If HK be drawn through V parallel to BG and meeting AB, A C in H, K respectively, HK is the diameter of the circular section of the cone made by a plane parallel to the base. Therefore Q V 2 = HV . VK. Then (1) for the parabola we have, by parallels and similar triangles, » HV:PV=BC:GA, and VK:PA = BC:BA.
