Classifying Two-Dimensional Figures by Examining Their Properties

This lesson teaches how to classify two-dimensional figures by examining their properties, such as the number of sides and angles. It explains the use of prefixes to determine the number of sides and describes different types of angles, including right, obtuse, and acute angles. The lesson also addresses common misunderstandings and applies classification to identify specific figures like trapezoids and heptagons.
