What is the relationship between VSEPR and polarity?

You need the VSEPR to figure out the polarity of a molecule. For example, knowing the AXE notation of a molecule can help you determine the polarity so if a molecule doesn't have polar bonds its nonpolar but if it has polar bonds it can be nonpolar only if :

a)All bonded atoms are identical

b)It is symmetrical, so it must include one of the following:
AX2 AX3 AX4 AX5 AX2E3 AX6 AX4E2 AX2E4

*Both requirements must be fulfilled for dipole moments to cancel (to be nonpolar)*
