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 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
