What is a 1000 sided shape called?

a chiliagon

A chiliagon is a polygon with 1000 sides. It is a regular polygon, which means that all sides have the same length, and all angles have the same measure. The interior angles of a chiliagon sum up to 179,820 degrees, which means that each angle measures approximately 179.82 degrees.

The perimeter of a chiliagon depends on the length of each side. If the length of a side is s, then the perimeter of a chiliagon would be 1000s. The area of a chiliagon also depends on the length of a side. It can be calculated using the formula:

Area = 250,000s^2cot(π/1000)

A chiliagon is a highly theoretical shape, and it is not found in nature. However, it is used in mathematical calculations and geometric proofs. It is also interesting to note that the term "chiliagon" comes from the Greek word "chilioi," which means "thousand," and "gonia," which means "angle."
