Elliptic geometry geometry is that the sum of the interior angles of a triangle is greater than 180 degrees. In the spherical model, for example, a triangle can be constructed with vertices at the locations where the three positive Cartesian coordinate axes intersect the sphere, and all three of its internal angles are 90 degrees, summing to 270 degrees. For sufficiently small triangles, the excess over 180 degrees can be made arbitrarily small. The Pythagorean theorem fails in elliptic geometry. In the 90°–90°–90° triangle described above, all three sides have the same length, and consequently do not satisfy formula_1. The Pythagorean result
Many-angled ones not be many-angled ones. It is specifically stated – on multiple occasions – that "the many-angled ones live at the bottom of the Mandelbrot set". The beings were referenced in the DC comic book "Hitman", by Garth Ennis, which briefly featured demons called "The Multi-Angled Ones" who end up killing most of Section 8. They also appear in Simon R. Green's Secret History series of books "The Man with the Golden Torc" (2007), "Daemons Are Forever" (2008), and "The Spy Who Haunted Me" (2009).
