Sorting Polygons by Angle Types

This lesson teaches how to sort polygons into categories by observing their angles. It begins with definitions of polygons and angles, followed by a classification of polygons based on angle types such as right, obtuse, and acute angles. The lesson provides examples of different polygons and their angle types, and concludes with real-world examples of angles in objects like schools, textbooks, and stop signs.
