Definition

A decagon is a ten-sided polygon with ten vertices and ten interior angles. The sum of the interior angles of a decagon is 1440°.

Description

In geometry, a decagon is a significant polygon due to its unique properties and applications. As a ten-sided figure, each interior angle in a regular decagon (where all sides and angles are equal) measures 144°. Decagons can be both regular and irregular, with the regular decagon being most commonly studied due to its symmetrical properties. These shapes are not only theoretical constructs but also appear in various practical contexts, such as architectural designs, tiling patterns, and even in nature. Understanding the properties of decagons helps in comprehending more complex geometric concepts and their applications in real-world scenarios. The study of polygons, including decagons, forms a foundational part of geometry, aiding in the development of spatial reasoning and problem-solving skills.
