Exploring Lines of Symmetry

The video tutorial introduces the concept of lines of symmetry, using examples from facial features and various geometric shapes like squares, rectangles, and circles. It explains how to identify and draw lines of symmetry, emphasizing that a square has four lines, a rectangle has two, and a circle has infinite lines of symmetry. The lesson includes practical exercises to evaluate symmetry in different shapes, encouraging students to apply their understanding.
