Polygon

A polygon is a flat, two-dimensional shape made up of straight line segments connected end to end. The line segments, called sides, meet at points called vertices. The shape is closed, meaning all sides connect to form a complete boundary. Examples include triangles, squares, and pentagons. Polygons can have many sides and angles, and their properties are studied in geometry to understand shape, size, and spatial relationships. They are fundamental in various fields, from architecture to computer graphics, providing a basic building block for more complex shapes and designs.
