Sign in to savethumb|400px|right|Some polygons of different kinds: open (excluding its boundary), boundary only (excluding interior), closed (including both boundary and interior), and self-intersecting. In geometry, a polygon () is a plane figure made up of line segments connected to form a closed polygonal chain.
AI overview
A polygon is a flat, closed shape made by connecting straight line segments end-to-end. Polygons are fundamental in geometry and appear everywhere in mathematics, design, and nature, making them essential for understanding how we measure and represent space.

thumb|400px|right|Some polygons of different kinds: open (excluding its boundary), boundary only (excluding interior), closed (including both boundary and interior), and self-intersecting. In geometry, a polygon () is a plane figure made up of line segments connected to form a closed polygonal chain.
The segments of a closed polygonal chain are called its edges or sides. The points where two edges meet are the polygon's vertices or corners. An '''n-gon' is a polygon with n sides; for example, a triangle is a 3-gon.
