Classifying Polygons Based on Perpendicular Lines

This video tutorial explains how polygons can be classified based on the presence or absence of perpendicular lines. It begins with an introduction to polygon properties and focuses on quadrilaterals, such as squares and rectangles, which have four pairs of perpendicular lines. The video then examines other quadrilaterals like rhombuses, which may lack perpendicular lines, and extends the discussion to pentagons and hexagons. The lesson concludes with a summary of how to classify polygons by their perpendicular line properties.
