Can someone explain line of symmetry in shapes?

A line of symmetry divides a shape into two identical halves that are mirror images of each other. When folded along this line, both sides match perfectly. Shapes can have one or multiple lines of symmetry, like a square (four) or a circle (infinite).

A line of symmetry in a shape is an imaginary line that divides the shape into two identical halves that are mirror images of each other. When a shape is folded along this line, both sides match exactly. Many geometric shapes, like squares and circles, have one or more lines of symmetry, which reflect balance and uniformity in design.
