Two-Dimensional Figures and Polygons

The video tutorial explains the properties of geometrical shapes, focusing on two-dimensional figures known as polygons. It defines polygons as closed shapes made of line segments and distinguishes them from other shapes like circles. Examples of polygons such as squares, rectangles, triangles, hexagons, and rhombuses are provided, while shapes with curves or open shapes are identified as non-polygons. The lesson concludes with a summary of polygon characteristics.

Describe a shape that is closed but not a polygon based on the properties discussed.
