## Summary

Polygon Definition and Properties

• 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 edges or sides, and the points where two edges meet are the polygon's vertices or corners.

• Polygons are primarily classified by the number of sides, and an n-gon is a polygon with n sides.

• A polygon may be simple, meaning it does not intersect itself, or self-intersecting, creating star polygons and other non-simple shapes.

• A polygon is a 2-dimensional example of the more general polytope in any number of dimensions.

• The word polygon derives from the Greek adjective πολύς (polús) 'much', 'many' and γωνία (gōnía) 'corner' or 'angle'.

• Polygons may be characterized by their convexity or type of non-convexity, such as a concave polygon.

• A polygon is regular if and only if it is both isogonal and isotoxal, or equivalently it is both cyclic and equilateral.

• The area of a simple polygon can be calculated using the shoelace formula or surveyor's formula.

• For any two simple polygons of equal area, the Bolyai–Gerwien theorem asserts that the first can be cut into polygonal pieces which can be reassembled to form the second polygon.

• The area of a regular polygon is given in terms of the radius r of its inscribed circle and its perimeter p.

• The coordinates of the centroid of a solid simple polygon are calculated using a formula that incorporates the signed value of the area.

• Individual polygons are named and classified according to the number of sides, combining a Greek-derived numerical prefix with the suffix -gon, such as pentagon and dodecagon.Polygons: Definition, Examples and Applications

• Polygons are two-dimensional geometric shapes consisting of straight lines that form a closed shape.

• The study of non-convex polygons was first carried out by Thomas Bradwardine in the 14th century.

• Polygons have been generalized to the complex plane by Geoffrey Colin Shephard in 1952.

• Polygons appear in nature, such as in rock formations and the wax honeycomb made by bees.

• Regular hexagons can occur when lava cools and forms tightly packed columns of basalt.

• In computer graphics, polygons are used as primitives for modeling and rendering.

• Any surface is modeled as a tessellation called a polygon mesh, which is a collection of polygons.

• The imaging system renders polygons in correct perspective for viewing on a display system.

• The point in polygon test is used in computer graphics and computational geometry to determine whether a given point lies inside a polygon.

• Polygons have a wide range of applications, including in computer graphics, architecture, and engineering.

• Understanding polygons is important for geometry, trigonometry, and other fields of mathematics.

• The study of polygons continues to evolve, with new applications and techniques being discovered all the time.
