Classifying Polygons by Sides and Regular or Irregular (Level 2)

This math topic focuses on practicing the classification of polygons. Students learn to identify different types of polygons, classify them by the number of sides they possess, and determine whether they are regular (all angles equal and all sides equal) or irregular (not all angles or sides are equal). The exercises include a variety of polygons like quadrilaterals, pentagons, hexagons, and octagons, enhancing their skills in recognizing and differentiating between these shapes based on their geometric properties. This forms part of a broader unit on 2D shape classification within geometry.
