RD Sharma Solutions for Class 8 Chapter 15 describes a polygon is a plane figure that is represented by a finite number of straight-line segments connected to form a closed polygonal chain or polygonal circuit. The solid plane region, the bounding circuit, or the two together, maybe called a polygon. A polygon is a closed curve formed by the line segment where (i) no two line segments intersect except at their endpoints and (ii) no two line segments with a common endpoint are coincident. Chapter Polygon deals with the topic of Polygon and its Classification, Terms Related to Polygons, Interior and Exterior of the Polygon, Convex and Concave Polygons, Regular and Irregular Polygon, Worksheet on Polygon and its Classification, Worksheet on Interior Angles of a Polygon, and Worksheet on Exterior Angles of a Polygon.
