quattuordeagonal

Quattuordeagonal refers to a polygon with fourteen sides. The prefix "quattuor-" is Latin for four, and "deca-" is Greek for ten, combining to signify fourteen. A quattuordeagonal polygon is also known as a tetradecagon.

Like any polygon, a quattuordeagonal can be regular or irregular. A regular quattuordeagonal has fourteen equal sides and fourteen equal interior angles. The sum of the interior angles of any quattuordeagonal, regardless of its regularity, can be calculated using the formula (n-2) * 180 degrees, where n is the number of sides. For a quattuordeagonal, this sum is (14-2) * 180 = 12 * 180 = 2160 degrees. In a regular quattuordeagonal, each interior angle measures 2160 / 14 = approximately 154.29 degrees.

The area of a regular quattuordeagonal with side length 's' can be calculated using the formula A = (14/4) * s^2 * cot(pi/14). The perimeter of a quattuordeagonal is simply the sum of the lengths of its fourteen sides. In the case of a regular quattuordeagonal, the perimeter is 14 * s.
