Point at infinity complex field, the set of points at infinity is a manifold. In artistic drawing and technical perspective, the projection on the picture plane of the point at infinity of a class of parallel lines is called their vanishing point. In hyperbolic geometry, points at infinity are typically named ideal points. Unlike Euclidean and elliptic geometries, each line has two points at infinity: given a line "l" and a point "P" not on "l", the right- and left-limiting parallels converge asymptotically to different points at infinity. All points at infinity together form the Cayley absolute or boundary of a hyperbolic plane.
The Devil's Point easiest route is to follow the path leading up the Coire Odhar from Corrour Bothy, on the eastern side of the mountain. To reach the bothy requires a long walk in; the most usual route is to follow the Lairig Ghru from Linn of Dee, a distance of some . The Devil's Point is often climbed along with Cairn Toul. Sgòr an Lochain Uaine, which lies to the north of Cairn Toul is sometimes called "The Angel's Peak", in contrast to The Devil's Point. The Devil's Point The Devil's Point (Scottish Gaelic: Bod an Deamhain) is a mountain in the
