I have prob w/ Circular Pattern command

I'm a newbie to SW w/ only few hrs on hand training. Sorry if I post this question in the wrong place.

My prob is when I tried to use Circular Patt on a feature @ 180deg (I used a sketch as the axis of rotation)

and the end product looked exact like a Mirror command. IE circular array of the letter "A" @ 180, #2 would

gimme an up-side-down "A". Please help & point me to the right direction. Thanks.
