What does it mean when dipoles "cancel out?"

Dipoles could cancel out if the are facing the same direction and if the atoms surrounding the central atom are all the same. This would mean that the electronegativity difference between the central atom and each of the bound atoms is the same. For example, with CO2, the dipole points toward Oxygen because it has a slight negative charge and Carbon has a slight positive charge (the dipole arrow will point in the direction of the more electronegative atom). The dipole moments are of the same strength and are pointing in opposite directions so they are cancelled out, and thus the overall molecule is nonpolar.
