Fold (or pretend to fold) an object in half in different ways, and if the edges and corners match exactly up to each other, that is a line of symmetry. If you want to count all the lines of symmetry, use the method above but tally the amount of lines of symmetry you count.
No because diagonal lines do not count. Even though they might fit perfectly inside the rectangle, but those don't count. Only lines going horizontally or vertically count as lines of symmetry. :)
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.
There are 6 lines of symmetry if you count sides and not just vertices. (=

nobody knows look at it and count jp jp
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

There is no such thing as 8 lines of symmetry. A circle, for example, has infinitely many lines of symmetry.
