a rectangle (think of a piece of paper)
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
A rectangle has exactly 2 lines of symmetry
I think the shape is a star
A parallelogram normally has no lines of symmetry unless it is in the shape of a rectangle which will then give it 2 lines of symmetry
it is when you use lines to split the shape equally
A rhombus is one example.
I believe that there is no such shape.
