Triangle of these conditions hold: (a) each of the angles is positive, and (b) the angles sum to 180°. If degenerate triangles are permitted, angles of 0° are permitted. Three positive angles "α", "β", and "γ", each of them less than 180°, are the angles of a triangle if and only if any one of the following conditions holds: the last equality applying only if none of the angles is 90° (so the tangent function's value is always finite). There are thousands of different constructions that find a special point associated with (and often inside) a triangle, satisfying some unique property:
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
