octoquadragintagonal
Octoquadragintagonal refers to a polygon with 84 sides. The prefix "octoquadraginta" combines "octo" meaning eight and "quadraginta" meaning forty, totaling forty-eight, which is then doubled to represent eighty-four. As with any polygon, an octoquadragintagonal shape has 84 straight sides and 84 vertices, where the sides meet. The sum of the interior angles of an octoquadragintagonal polygon can be calculated using the formula (n-2) * 180 degrees, where n is the number of sides. For an octoquadragintagonal polygon, this would be (84-2) * 180 = 82 * 180 = 14760 degrees. Each interior angle of a regular octoquadragintagonal polygon, where all sides and angles are equal, would measure 14760 / 84 = 175.71 degrees. The number of diagonals in an octoquadragintagonal polygon is given by the formula n(n-3)/2, which for n=84 is 84(84-3)/2 = 84*81/2 = 3402 diagonals. This term is primarily used in geometry and mathematics to describe such a specific shape.
