novencentagonal

Novencentagonal refers to a polygon with 90 sides. The term is derived from the Latin word "novem" meaning nine, and the Greek word "kentron" meaning angle or corner, combined with the suffix "-al" indicating "relating to". A novencentagon is a specific type of polygon in Euclidean geometry. Like all polygons, it is a closed shape formed by straight line segments connected end to end. The sum of the interior angles of any novencentagon is (90-2) * 180 degrees, which equals 14400 degrees. If the novencentagon is regular, meaning all its sides are of equal length and all its interior angles are equal, then each interior angle measures 14400 / 90 degrees, or 160 degrees. The exterior angles of a regular novencentagon each measure 360 / 90 degrees, which is 4 degrees. The number of diagonals in a novencentagon can be calculated using the formula n(n-3)/2, where n is the number of sides. For a novencentagon, this would be 90(90-3)/2, resulting in 90 * 87 / 2, or 3915 diagonals.
