Polygon

A flat shape with many straight sides

A polygon is a two-dimensional (flat) closed figure made up of straight line segments. It has three or more straight sides and angles, and each side intersects with exactly two others at its endpoints. The term polygon comes from Greek, where poly means many and gon means angle.

Polygons can have different names depending on the number of sides they have, such as triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), hexagons (6 sides), and so on. Polygons can be convex or concave, depending on the direction of the angles.

Convex polygons have all their interior angles less than 180 degrees, while concave polygons have at least one interior angle greater than 180 degrees. The sum of the interior angles of a polygon with n sides is equal to (n-2) x 180 degrees.

Examples of polygons include squares, rectangles, triangles, pentagons, hexagons, and octagons. Polygons are used in many areas of mathematics, including geometry, trigonometry, calculus, and statistics, as well as in real-life applications such as architecture, construction, and engineering.
