To determine molecular shape.
The lone pair pushes bonding electron pairs away.
The lone pair pushes bonding electron pairs away.
The shape of PF3 is trigonal bipyramidal. The geometric diagram determines this shape. Its electron domain geometry and molecular geometry are also the same.
The molecular shape is square pyramidal because it has five ligands and one lone pair and the bond angle are 90,<120. Also, it has no dipole moment and the electron group geometry is octahedral.
The VSEPR model is used mainly to determine molecular shape.
It would have electron geometry trigonal planar, and a molecular geometry of Bent.

Same as its molecular shape; tetrahedral.

Trigonal pyramid will be its molecular shape. It will have tetrahedral electron domain geometry.
