Identifying Line Symmetry in Regular Polygons

This lesson teaches how to identify line symmetry in regular polygons by folding them into symmetrical parts. It covers the concept of line symmetry, explaining the three types: horizontal, vertical, and diagonal. The lesson provides examples using equilateral triangles, squares, and hexagons, showing how the number of lines of symmetry corresponds to the number of sides in these regular polygons.
