novemdecagon

A novemdecagon is a polygon with nineteen sides and nineteen vertices. In a regular novemdecagon, all sides are of equal length and all interior angles are equal. The sum of the interior angles of any novemdecagon, regular or irregular, can be calculated using the formula (n-2) * 180 degrees, where n is the number of sides. For a novemdecagon, this sum is (19-2) * 180 = 17 * 180 = 3060 degrees.

The measure of each interior angle in a regular novemdecagon is 3060 degrees / 19, which is approximately 161.05 degrees. The exterior angle of a regular novemdecagon is 360 degrees / 19, approximately 18.95 degrees. A novemdecagon is a type of polygon, and the prefix "novemdec-" comes from Latin, meaning nineteen. While constructing a regular novemdecagon using only a compass and straightedge is possible in theory, it is a complex geometrical challenge.
