A polygon is a two-dimensional geometric shape with straight sides and angles.
It is a closed figure formed by connecting consecutive line segments. Polygons can have various numbers of sides, and their names are based on the number of sides they possess.
For example, a triangle has three sides, a quadrilateral has four sides, and a pentagon has five sides.
Polygons are fundamental in geometry and are used to describe and analyze various shapes and structures in mathematics and the physical world.
