A circle has infinite lines of symmetry. Any diameter of the circle can serve as a line of symmetry, dividing the circle into two identical halves, which makes it unique among other geometric shapes.

Class 6 Mathematics Chapter 9 Symmetry question answer
A circle has infinite lines of symmetry because every diameter divides it into two equal halves, which are mirror images of each other. Unlike polygons, where the number of symmetry lines is fixed, a circle’s symmetry is continuous, making it unique in geometry. This allows the circle to maintain its symmetry at any angle of rotation or reflection, and it is commonly used in designs requiring perfect balance and repetition, such as wheels or circular patterns.
