Right triangle right triangle, see the hyperbolic triangle of a hyperbolic sector. The values of the trigonometric functions can be evaluated exactly for certain angles using right triangles with special angles. These include the "30-60-90 triangle" which can be used to evaluate the trigonometric functions for any multiple of π/6, and the "45-45-90 triangle" which can be used to evaluate the trigonometric functions for any multiple of π/4. Let "H", "G", and "A" be the harmonic mean, the geometric mean, and the arithmetic mean of two positive numbers "a" and "b" with "a" > "b". If a right triangle has legs "H"
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). In the Marvel Comics cosmic crossover event "Realm of Kings," written by Dan Abnett and Andy
