What is the number of line(s) of symmetry in a circle?
Infinite
The line of symmetry is defined as a line which divides an image into two equal halves.
Diameter is the line of symmetry of a circle. A circle has an infinite number of diameters.
From the figure, AB divides the circle into two equal halves, where AB is the diameter of the circle.
Therefore, it will have an infinite number of lines of symmetry.
