not all shapes have lines of symmetry. one example is a triangle.

Three dimensional shapes, generally, don't have lines of symmetry, but a circle has an infinite number is symmetry lines. 3D shapes also don't have rotational symmetry either, but a circle has an infinite number of that as well.
Most of them.

No. Asymmetric shapes do not have any lines (or planes) of symmetry.

Most shapes do not have lines of symmetry so why should it come as a surprise that a parallelogram has none?
Equilateral triangle.
