Casey's Theorems deals with the tangents of five of these. Feuerbach's theorem involves the nine-point one.
Casey's Theorems deals with the tangents of five of these. Feuerbach's theorem involves the nine-point one. A great one is a straight line in (*) gnomonic projection. This shape results from the intersection of a cone and a plane perpendicular to the symmetry of the cone. A more common equation for it is x squared plus y squared equals r squared, where r is the radius. For 10 points, name this shape consisting of points that are equidistant from the center, whose circumference is given by 2 pi r.
