Exploring Regular and Irregular Polygons

The video tutorial explains the differences between regular and irregular polygons. Regular polygons have equal sides and angles, while irregular polygons do not. The tutorial includes examples and exercises to help identify these types of polygons, such as squares, triangles, pentagons, and rhombuses. The lesson concludes with a summary of the characteristics of regular polygons.

What defines a polygon?

• A three-dimensional object

• An open shape with no specific properties

• A closed two-dimensional shape made up of line segments

• A shape with curved lines
