If there are designated shapes already, does this mean all atoms have fixed angles?

There are not fixed angles, because it all depends on the different elements that are bound to the central atom (or whether there are lone pairs), which create different electron repulsions. If all the atoms attached are the same (i.e. CH4), then the angles would be the same, but the angles vary between different molecules. VSPER models give you a good generalized idea on what the angles would be, but these would not be the same angles in every case.
