What are the names of different types of polygons based on the number of sides

The video tutorial explains how to classify polygons based on the number of sides they have. It begins with a definition of polygons, highlighting their properties such as being closed figures with straight sides and vertices. The tutorial then classifies polygons into categories like triangles, quadrilaterals, pentagons, and more, up to dodecagons. It also covers naming conventions for polygons with more than 12 sides, using the term 'ngon' to simplify. The video emphasizes the importance of knowing these classifications for solving geometry problems.
