Symmetry explores the concept of balance and harmony in shapes and nature. A figure is considered symmetrical if it can be folded into two identical halves that match perfectly. The fold line is called the Line of Symmetry. Students learn to identify objects with one, two, or multiple lines of symmetry in everyday items, architecture, and art. The chapter also introduces Mirror Reflection, where the image and the object are symmetrical with respect to the mirror. This topic enhances artistic creativity and geometric observation skills in students.
