10000gon
A 10000-gon, also known as a myriagon, is a polygon with 10,000 sides. It is a type of regular polygon, meaning all its sides and angles are equal. The term "myriagon" comes from the Greek word "myria," which means 10,000. The internal angle of a regular 10000-gon can be calculated using the formula for the internal angle of a regular polygon, which is (n-2) * 180 / n, where n is the number of sides. For a 10000-gon, this would be (10000-2) * 180 / 10000, which simplifies to 179.96 degrees. The external angle, which is the angle between the extensions of two adjacent sides, would be 0.04 degrees. Due to its high number of sides, a 10000-gon appears nearly circular when drawn. In practical applications, such a polygon is rarely used due to its complexity and the fact that it closely approximates a circle. However, it is an interesting concept in geometry and mathematics.
