Equiangular lines - Wikipedia, the free encyclopedia
In geometry, a set of lines in Euclidean space is called equiangular if every pair of lines makes the same angle. Equiangular lines are related to two-graphs. Given a set of equiangular lines, let ...

The equiangular spiral was first considered in 1638 by Descartes, who started from the property s = a.r. Evangelista Torricelli, who died in 1647, worked on it independently and used for a definition the fact that the radii are in geometric progression if the angles increase uniformly.

A Property of Equiangular Polygons: the sum of distances of from a point to the sides of an equiangular polygon is invariant of a polygon ... Quite obviously, an equiangular polygon can be embedded into a regular polygon with parallel sides. This can be done in a continuum of ways. But fix a suitable regular polygon,

Given a line segment AB, the loci of points P such that the angle APB has a constant value are circular arcs that pass through the points A and B. As a special case of this we have the well-known fact that if APB is a In general, if AB is any chord of a circle, ... (Note that if the chord is not a diameter of the circle,
