In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, "ten angles") is a ten-sided polygon or 10-gon. [1] The total sum of the interior angles of a simple decagon is 1440°.

Meaning of Decagon A decagon is a ten-sided polygon with ten vertices and ten angles. Thus, a decagon shape can be defined as a polygon having ten sides, ten interior angles, and ten …

In geometry, a polygon having ten sides (or a ten-sided polygon) is called a decagon or ten-gon. It also has ten vertices and ten angles.

A decagon gets its name from the Ancient Greek word "deka-" meaning "ten" and "gonia" meaning corner or angle. Thus, a decagon is a 10-sided closed-figure with 10 corners and …

Aug 3, 2023 · A decagon is a polygon with ten sides and ten angles. The term ‘decagon’ is derived from the Latin word ‘decagonum’ where ‘deca’ means ten, and ‘gonium’ means ‘angles’.

In this article, we’ll take a closer look at what a decagon is, highlight its key properties, and explain the different types of decagons. We’ll also share helpful formulas for solving decagon-related …

A decagon is a polygon with ten sides, ten angles, and ten vertices. Decagons can be classified as regular (equal sides and angles) or irregular, and also as convex or concave.

Learn about decagons with easy explanations, properties, formulas, and interactive quizzes. Perfect for K-5 students studying geometry and shapes.

Dec 3, 2025 · A decagon is a ten-sided polygon. Several special types of decagons are illustrated above. In particular, a decagon with vertices equally spaced around a circle and with all sides …

To find the exterior angle of a regular decagon, we use the fact that the exterior angle forms a linear pair with the interior angle, so in general it is given by the formula 180-interior angle. …
