Tetrahedral and its polarity

[Angeline 3E]

im confused because a tetrahedral has bonds in different planes (like theres one w the dotted line and the solid line) does this means any molecule with a tetrahedral structure is always polar because how will the dipoles cancel out?

if all the bonded atoms are the same ( ex. CCl4, CH4) then there is no dipole

does this also apply to trigonal bipyramidal and octahedral?

yep, for those the same thing applies. If they're all the same element around the central atom then its non-polar

If you have a molecule like CHF3, it will be polar because not all of the atoms surrounding the C are the same, but will that affect the bond angles or do you still assume that it is 109.5

I believe it will have bond angles of 109.5 since the shape is still tetrahedral.

To add on, if the atoms surrounding the central atom is not the same, it will have dipole moment because the different surrounding atoms will have various electronegativity, therefore the dipole forces will not completely cancel out.
