S has 6 valence electrons. In $SF_4$: 4 bonding pairs + 1 lone pair = 5 electron domains.
$$Electron geometry: Trigonal bipyramidal$$
$$Molecular geometry: See-saw (seesaw)$$
Bond angles: $\approx 101.6°$ (axial–equatorial) and $\approx 173°$ (axial–axial), both compressed from ideal due to lone pair repulsion.
$$See-saw shape; bond angles \approx 101.6° and 173°$$

Saved me before my mock test. Much clearer than my coaching notes.

How do we know the approximation is valid here?
A
Underrated solution. The way you set it up makes it almost obvious.
