A tetradecagon is a polygon with 14 sides and 14 angles. The term comes from the Greek words "tetra," meaning four, and "deca," meaning ten, combined to indicate fourteen. Each internal angle of a regular tetradecagon measures approximately 128.57 degrees, and the sum of all internal angles is 1,440 degrees. Tetradecagons can be found in various fields, including mathematics and architecture. They are studied in geometry, where properties such as symmetry and area are analyzed. The concept of a tetradecagon is also related to other polygons, such as decagon (10 sides) and hexadecagon (16 sides).
