What is the difference between line of reflection and line of symmetry?

a line of symetry can be applied to one shape but cannot go between two shapes unless those two shapes are infact a part of one larger, symetrical shape.

a line of reflection goes between two shapes. so O l O this is two circles with a line of reflection in between them. if there was a line of reflection between two e's then one of the e's would have to be a backwards e.
