There is an infinite number of lines across a circle that form two symmetric half-circles.
They have infinite lines of symmetry.
If you are talking about a perfect circle, it has wan infinite number if lines of symmetry. If you are talking about and actual lower case o, then the answer is two.
A nephroid has 2 lines of symmetry.
it has five lines of symmetry
10 lines of symmetry
4 Lines of symmetry
2 lines OF SYMMETRY
2 lines of symmetry
It has 2 lines of symmetry.
no lines of symmetry
2 lines of symmetry
A basketball has an infinite number of lines of symmetry. This is because a basketball is a perfect sphere, and any plane passing through its center will divide it into two equal halves that are symmetrical. Therefore, there are an infinite number of lines of symmetry that can be drawn on a basketball.
