Quattuorcentagonal
Quattuorcentagonal refers to a polygon with 400 sides. The term is derived from Latin, with "quattuor" meaning four and "centum" meaning hundred, combined to signify four hundred. A quattuorcentagonal polygon, like any regular polygon, has sides of equal length and interior angles of equal measure. The sum of the interior angles of any polygon can be calculated using the formula (n-2) * 180 degrees, where 'n' is the number of sides. For a quattuorcentagonal polygon, this would be (400-2) * 180 = 398 * 180 = 71640 degrees. Each interior angle of a regular quattuorcentagonal polygon measures 71640 / 400 = 179.1 degrees. In Euclidean geometry, it is theoretically possible to construct a regular quattuorcentagonal polygon. However, constructing such a polygon precisely with traditional geometric tools like a compass and straightedge is practically impossible due to its very large number of sides. The complexity increases significantly with each additional side. The properties of a quattuorcentagonal polygon are mathematically defined, but it is not a shape encountered in everyday life or common geometrical discussions.
