| porism | 1. <geometry> A proposition affirming the possibility of finding such conditions as will render a certain determinate problem indeterminate or capable of innumerable solutions. 2. <geometry> A corollary. Three books of porisms of Euclid have been lost, but several attempts to determine the nature of these propositions and to restore them have been made by modern geometers. Origin: Gr. A thing procured, a deduction from a demonstration, fr. To bring, provide: cf. F. Porisme. Source: Websters Dictionary (01 Mar 1998) |
