Identifying Regular vs Irregular Polygons

This video tutorial teaches how to identify regular and irregular polygons. It explains that regular polygons have equal sides and angles, while irregular polygons have unequal sides and angles. The video provides examples of both types and includes practice exercises to help viewers identify these shapes. The lesson concludes with a quiz to test the knowledge gained.
