2. What is Symmetry?
Symmetry is the exact matching of shapes or figures on opposite sides of dividing lines or around a central point.
The dividing line is called lines of symmetry.
Symmetry surrounds us. It is found in art and architecture, music, plants, insects, animals – and humans.
Certain shapes, particularly polygons and circles have many lines of symmetry.
