consider a regular $$2n-gon$$ show that $$R_{180}$$ commutes with all other rotations and flips. for example, below two sequence of transformations give the same final effect : 1) a. rotate 180 b. flip over the symmetry line passing through vertex A 2) a. flip over the symmetry line passing through vertex A b. rotate 180 in other words, show that the order doesn't matter if one transformation is $$R_{180}$$
