Classifying Polygons by Sides and Regular or Irregular

Level 1

This math topic focuses on classifying polygons based on the number of sides and whether they are regular or irregular. The problems help build foundational skills in identifying different types of polygons such as quadrilaterals, pentagons, hexagons, and octagons, categorizing them based on symmetry and equal angles and sides. These exercises are an introductory part of a larger unit on Geometry Basics, suitable for understanding shape characteristics and properties.

Are these polygons regular or irregular

First let's count the sides. They both have 5 sides, so they both are pentagons

The first one has different side lengths and angles, so it is irregular. The second one has the same side lengths and angles, so it is regular
