An icosagon is a geometric shape known as a polygon, precisely a 20-sided polygon. The prefix “icosi-” is derived from the Greek word “eikosi,” meaning twenty. The term is used in the context of geometry to describe a two-dimensional figure with twenty straight sides and twenty angles. Each angle in an icosagon measures 162 degrees in an ideal, regular icosagon, assuming the sides are of equal length.

In a regular icosagon, all the sides and angles are identical, making it a regular polygon. The sum of the internal angles in any icosagon is determined by the formula (n-2) × 180 degrees, where n represents the number of sides. Therefore, the sum of the internal angles in an icosagon is (20-2) × 180 = 3,240 degrees. Additionally, the exterior angle of a regular icosagon is 18 degrees.

Icosagons can be found in various fields, including architecture and design, where they can be used in patterns or structures to create visually appealing and symmetrical designs. Understanding the properties and mathematical aspects of the icosagon is fundamental in geometry and serves as a foundation for further exploration into the properties of polygons.
