Equilateral pentagon of δ can be seen from the figure: Simplifying, δ is obtained as function of α and β: The remaining angles of the pentagon can be found geometrically: The remaining angles of the orange and blue triangles are readily found by noting that two angles of an isosceles triangle are equal while all three angles sum to 180°. Then formula_7 and the two remaining angles of the green triangle can be found from four equations stating that the sum of the angles of the pentagon is 540°, the sum of the angles of the green triangle is 180°, the angle
Victims of Terrorist Attack on the Pentagon Memorial all the victims of the terrorist attack on the Pentagon qualified for burial at Arlington National Cemetery. Families of those who did often chose to bury the remains of their loved ones at a private cemetery. Sixty-four individuals who died at the Pentagon were buried at Arlington, and 57 of them were interred in Section 64, their headstones facing the Pentagon about away to the southeast (visible through a few trees).
