THE CENTER PAGE COMMAND IS ACCESSED THROUGH WHAT MENU?

It would depend on the word processor, on mine, it is through the Format menu.

If you are taking a word processing class, one of the first things you should have been taught is to have the Caps Lock key off.

It might already be on your tool bar. Align left symbol would look something like this:

I don't know if I can duplicate the align center symbol, but I will try.

I hope this helps a little more. Thanks for asking.
