DECAGON Meaning and
Definition
-
A decagon is a polygon that consists of ten sides and ten angles. It is a two-dimensional geometric shape that belongs to the family of polygons. The term "decagon" is derived from the Latin word "decem," which means ten, and the Greek word "gonia," which means angle.
In a decagon, each side connects to the adjacent sides through endpoints called vertices. The sum of the interior angles of a decagon is equal to 1440 degrees, and each interior angle measures 144 degrees. Conversely, the exterior angles of a decagon sum up to 360 degrees, with each individual exterior angle measuring 36 degrees.
A regular decagon is a decagon that has equal sides and equal angles. All the sides of a regular decagon are congruent, and all the interior angles have the same measure. The formula to calculate the measure of each interior angle in a regular decagon is 180° × (n-2)/n, where n represents the number of sides, in this case, 10. Consequently, each interior angle in a regular decagon measures 144 degrees.
Decagons can be found in various contexts, such as geometric shapes, architecture, art, and mathematics. Their symmetrical and well-defined structure make them visually appealing, often used in designs, ornaments, and patterns. The study of decagons and other polygons is an essential topic in geometry, providing a foundation for understanding more complex figures and mathematical principles.
