A circle has an unlimited number of lines of symmetry. These lines are called the diameter. Why does a circle have an unlimited number of lines of symmetry? It's because a circle has a constant diameter regardless of where the diameter is measured from.

A rhombus has two lines of symmetry. They are also called its diagonals. Suppose there is a rhombus ABCD AC and BD are its lines of symmetry.

a circle
A nephroid has 2 lines of symmetry.
it has five lines of symmetry
Equilateral Triangles (3 lines of symmetry)Rectangles (at least 2 lines of symmetry)Squares (4 lines of symmetry)Rhombuses (at least 2 lines of symmetry)Any regular polygon (at least 5 lines of symmetry)
it has no lines of symmetry
A parallelagram can be a square, which has four lines of symmetry or a rectangle which has two lines of symmetry but the generic parallelagram has zero lines of symmetry
There is no such thing as 8 lines of symmetry. A circle, for example, has infinitely many lines of symmetry.
