$\ce{CF4}$. My thoughts: My first line of thought is that both of these molecules are symmetrical (the vectors from each individual atom naturally canceled each other out) with no lone pairs of electrons.Now I knew that just because they were symmetrical didn't automatically meant that they were non-polar.\ce{CF4}$: As you can see this molecules adopts a tetrahedral geometry which is perfectly symmetrical in every direction and so the dipoles of the four $\ce{C-F}$ bonds cancel out, leaving no overall dipole. $\ce{CHF3}$:
