I do not understand rigid symmetry. I read it in the book several times and it is quite unclear I am not sure who I am speaking to ...if you have a clear plastic cover like the one that you use in a 3-ring binder and put a paper in it...take a marker and make a shape on a piece of paper. Lay the plastic over it and trace the exact shape from the paper onto the plastic. Now rigid symmetry occurs when you now move that plastic and can place it else where and it lines up perfectly. Webster tells us: "a rigid motion of a geometric figure that determines a one-to-one mapping onto itself" this definition is expressing what I said above. Not sure if this helps but we can go over this before the quiz if you want.
