2 d shapes_presentation
The document defines and categorizes different 2D shapes. It discusses polygons, which are 2D shapes with straight sides, and divides them into regular polygons with equal length sides and angles or irregular polygons that are not equal. Non-polygons have at least one curved side and include circles, ovals, and ellipses. Various regular and irregular polygons are listed out by number of sides from 3 to 12 sides.
