                C.  1.  Do any letters of English alphabet have rotational symmetry? Write the

                          letters with their order of symmetry.

                     2.  Which of the digits from 0 to 9 have rotational symmetry?
                     3.  What order of rotational symmetry does a circle have?


                D.  Find the order of rotational symmetry of a regular hexagon. Draw rough
                     sketches of it.
