resonance structures in molecular structures

Just to clarify, since bonds are treated the same in terms of regions of electron density in the vsepr model, it doesn’t matter what resonance structure is used right?

Yes, I don't think it matters!

Yep. It doesn't matter. In an example in the textbook, only one of the resonance structures of the carbonate ion was used to figure out what the resulting shape of the molecule is.

Resonance structures would not matter as the molecule still maintains the same number of electron density regions based on repulsion forces and the same number of bonds formed is also maintained. The places in which the electron density would change but the bond angles would still be maintained in the new orientation.

Yes since the number of bonds in a molecule whether that be single, double, or triple all equal a single electron density region resonance structure won't matter.
