This is the same case for the octahedral shape of SF4Cl2. If the pull from the polar bonds in a molecule do not cancel each other out, the molecule is polar. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death. The geometry is triagonal planar and dipole moment of 2 bonds cancel the third one hence resultant dipole moment is zero. Pick "ionic" in that case). It explains how to draw the lewis structure of NO2 and how to determine how many valence electrons it has. NO2 (or nitrogen dioxide) is neutral as a gas, but can easily become NO2- (nitrite ion) in solution, demonstrating its polar nature.
