The Jerabek one is the isogonal conjugate of the Euler line while the Keipert one provides the general solution to Lemoine's problem.
The Jerabek one is the isogonal conjugate of the Euler line while the Keipert one provides the general solution to Lemoine's problem. The Fuerbach point is the center of a rectangular one, while the Poincare disk of this type has a metric given by "dx squared plus dy squared over quantity one minus x square minus y squared." One of them can be constructed from two Dandelin spheres touching the opposite napes of a cone, and a parabaloid of this type is a quadratic surface with equation "z equals y squared over b squared minus x squared over a squared." Also known as the type of non-Euclidean geometry discovered by Bolya and Lobachevsky, for ten points, identify this conic section, defined as the set of all points the difference in whose distance from two fixed foci is a constant.
