Geometry around the central atom

Would the geometry around the central atom take into account the lone pairs as well or do we just leave that out and only count the bonding pairs? I'm guessing it does? This is just to double check.

Yes it takes into account lone pairs cause they exert a negative charge cloud, repelling other bonded electrons.
Eg h2o is a bent molecule due to lone pair on oxygen

Thanks, I guess I should have  reworded it, because that wasn't my question. Sorry lol!
I wanted to say does water classify as having a bent or tetrahedral geometry given that if we consider the lone pairs it is tetrahedral but if we only consider bonding electrons it is tetrahedral.

I know for sure that it would have a tetrahedral electron pair geometry, and bent molecular geometry, but I was doing some questions where it didn't have answers and the questions just asked what is the geometry of the central atom?
