Re: How to center a circle?

I want to thank all of you for responding.
Well, what's the conclusion? If you all say that the circle is
centered who am I to disagree.
It is somewhat troublesome that apparently I cannot trust my own eyes
but, as I said, who am I to disagree.
@et99: Yes, I have always had rather strong glasses but so far I had
never have any reason to mistrust my perception. Ok, it sems that
there always is  a first time.
Maybe I should attribute it to age - not a very pleasant thought
either. Well ...
Many thanks again
