Identifying Line Symmetry in Irregular Polygons

This lesson teaches how to identify line symmetry in irregular polygons by folding them into matching parts. It covers three types of symmetry: horizontal, vertical, and diagonal. The video addresses common misunderstandings, such as incorrect placement of symmetry lines, and explains the differences between regular and irregular polygons. Examples include analyzing symmetry in shapes like arrows and lightning bolts, highlighting that irregular polygons may have fewer lines of symmetry due to non-congruent sides and angles.
