Although there are many kinds of symmetry, elementary school generally presents only reflective symmetry (or “mirror symmetry”). More intrepid experiments give other interesting results. Testing the role of vertical symmetry in letter matching. If the pattern was folded on the dividing line, the two sides would match up perfectly." Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License. The result that one sees — half of the original and the mirror image of that half — exactly matches the original figure. A vertical mirror plane that bisects the angle between two C 2 axes is called a dihedral mirror plane, σ d. σ symmetry is indicated as a plane on molecules; since they often bisect atoms, which should be clearly indicated.
