Dear Dr. Elaine
Thanks for your help. I am able to draw the symmetry axis, and can you let
me know how can I change the representation of the drawn vector, its color
and diameter. and If  I make another copy of the same vector how can I move
the second vector to a particular axis a by given rotation angle.
