This mini-lesson is an introduction to the basics of a polygon and will help learning about polygons. Polygon is a closed plane figure made up of several line segments that are joined together. The polygons are many-sided figures, and these are named according to the number of sides and angles they have. The most commonly known polygons are the triangle, the rectangle, and the square. You'll learn here with the help of video, and some examples with solution about the important properties of polygons and their relationship. Polygons also have diagonals, which are segments that join two vertices but no sides. It explains further about vertex of a polygon, sides of a polygon and the angles formed by it. E.g. A vertex is an endpoint of a line segment that forms a polygon. The line segments which form a polygon are called its sides and the angles formed by the line segments are known as the interior angles of a polygon. Polygons are named according to the number of sides and angles they have. For example, Triangle: 3 sides and 3 angles, Quadrilateral: 4 sides and 4 angles, Pentagon: 5 sides and 5 angles etc. In hexagon*ABCDEF*, the vertices are *A*, *B*, *C*, *D*, *E* and *F*, the sides are *AB*, *BC*, *CD*, *DE*, *EF*, *FA*, and the angles are *A*, *B*, *C*, *D*, *E* and *F*.
