Equilateral triangle terms of side length "a" can be derived directly using the Pythagorean theorem or using trigonometry. The area of a triangle is half of one side "a" times the height "h" from that side: The legs of either right triangle formed by an altitude of the equilateral triangle are half of the base "a", and the hypotenuse is the side "a" of the equilateral triangle. The height of an equilateral triangle can be found using the Pythagorean theorem so that Substituting "h" into the area formula (1/2)"ah" gives the area formula for the equilateral triangle: Using trigonometry, the area of
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
