Mathematical polygon is a symbolic figure composed of line segments, and it is also an important concept in mathematics. A polygon is a closed figure composed of straight line segments on a plane. Each side of a polygon is connected with two vertices, and there are several internal angles and corresponding degrees of internal angles in the polygon. Polygons can be regular polygons and non-regular polygons, and there are also different classification methods.

Mathematical polygons are widely used in geometry, graphics, computer science, physics and engineering. In geometry, polygons are the basic units of area and perimeter. In computer science, polygons can be used to model and render three-dimensional graphics, and are also the research objects of computational geometry and computer graphics. In physics, the properties of polygons are used to describe the lattice structure of polycrystalline bodies. In engineering, polygons can be used to make mechanical parts and building components.

Mathematical polygons also play an important role in mathematics education. Polygon is an important basic knowledge in junior high school mathematics class, involving concepts such as perimeter, area, angle and similarity. By studying the nature and application of polygons, students can improve their logical thinking ability and geometric intuition ability, and also lay a solid foundation for learning higher-level mathematical knowledge in the future. Therefore, the position of mathematical polygons in mathematics education can not be ignored.
