Line of Symmetry in Regular Polygons

The video tutorial explains the concept of regular polygons, which have equal sides and angles, and explores their lines of symmetry. It uses examples of a square, equilateral triangle, regular pentagon, hexagon, and octagon to illustrate how symmetry works in these shapes. Each polygon's lines of symmetry are identified and discussed, highlighting the symmetrical properties of regular polygons.
