What is hectogon?

A hectogon is a polygon with 100 sides. The sum of the internal angles in a hectogon is equal to (100 - 2) × 180 degrees, which is 17,640 degrees. A regular hectogon has equal side lengths and equal interior angles. The formula for calculating the interior angle of a regular hectogon is (n - 2) × 180 / n, where n is the number of sides, so for a regular hectogon this would be (100-2) x 180/100 = 176.4 degrees. A hectogon is a rare shape that is not commonly used in practical applications, but it is frequently studied in mathematics and geometry.
