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 Many-angled ones The many-angled ones are fictional other-dimensional beings linked to the Cthulhu Mythos. They first appeared in Grant Morrison's story "Zenith", which appeared in the British comics anthology "2000 AD". In "Zenith", they are known as the Lloigor, a direct reference to creatures from the Cthulhu Mythos. However, they appear somewhat different from the Cthulhu Mythos entities. In the comic, the many-angled ones plan to impose rigid geometrical order on the whole universe, essentially reducing it to clockwork. The many-angled ones exist in a space with more dimensions than our own; hence, they appear to be "many angled". As
