Victims of Terrorist Attack on the Pentagon Memorial excluded from the burial so that there was no possibility that any terrorist remains were included. These terrorist and commingled remains were turned over to the Federal Bureau of Investigation (FBI) in February 2002. The FBI said the remains were "disposed of in a dignified manner'", although a very small amount of suspected terrorist remains were retained to aid in later criminal prosecutions. The Victims of Terrorist Attack on the Pentagon Memorial was dedicated on September 12, 2002. A funeral service for the 30 victims was held at the Arlington Memorial Amphitheater, the first time the amphitheater had held such
Pentagon determine the length of this side, the two right triangles "DCM" and "QCM" are depicted below the circle. Using Pythagoras' theorem and two sides, the hypotenuse of the larger triangle is found as formula_11. Side "h" of the smaller triangle then is found using the half-angle formula: where cosine and sine of "ϕ" are known from the larger triangle. The result is: With this side known, attention turns to the lower diagram to find the side "s" of the regular pentagon. First, side "a" of the right-hand triangle is found using Pythagoras' theorem again: Then "s" is found using Pythagoras'
