parallelogram
If you draw a diagonal line from corner to corner of a parallelogram, that is a line of symmetry.
none (well if you slant the mirror, then it would be two) why - because that's the parallelogram's theory :)
A parallelogram has no lines of symmetry unless it is a square, a rectangle or a rhombus.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
Squares, which are parallelograms, have four lines of symmetry. Rectangles have only two. Rhombi have two lines of symmetry. Generic parallelograms don't have any lines of symmetry.None normally unless it is in the shape of a rectangle in which case it will have 2 lines of symmetry
A parallelogram need have no lines of symmetry.
a rhombus and a square. a square can be a parallelogram but a parallelogram cannot be a square. a rhombus cannot be a square but a square can be a rhombus. * * * * * A rhombus does not have any lines of symmetry, only a square has two.
a parallelogram has 2 lines of symmetry
There are 0 lines of symmetry in a parallelogram.

a trapezoid has a pair of symmetry lines but a square diamond or parallelogram all sides are parallel
A parallelogram.
A parallelogram.
a square has more then three lines of symmetry, but I don't think a parrellelogram with only two parallel sides can
