I looked up Tudor rose in Google Image Search, and by my count, it actually has 5 lines of symmetry. Each line starts from one of the tips and cuts the rose in half. It is similar to a regular pentagon.
2 lines of symmetry
A nephroid has 2 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
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
5 lines
It would depend on the number of petals. For instance if a flower had five petals, it would have five lines of symmetry. You could divide it five ways (with lines) and each time you divide it each half is even with the other.

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.
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
5 lines
i think 4 because there are 8 petals half of eight is 4
Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.
