is sulfur hexafluoride non polar or polar?

and how can you determine whether any molecule is polar or non polar? do the factors include the molecular formula, lewis structure, shape, and/or bong angle, etc? please explain as clearly and as much as possible, thank you!

Update:

Also, where the polar arrows are on the hexafluoride lewis structure diagram, and how you would put arrows on other molecules

    SF6 is non polar. While each S-F bond is, by itself, highly polar, since the molecule is arranged in an octahedral geometry the polarity of each bond exactly cancels. This may make a little more sense if you look at the structure.

    This is the same reason why CH3Cl is polar, but CCl4 is non-polar. In the first case, the more polar C-Cl bond is not canceled out by the relatively non-polar C-H bonds. In the second, the net effect is as if there was no polarity to the molecule at all.
