							Lone pair =1 Bond pair =3 so it is sp3 hybridised it geometry is tetrahedral and shape is trigonal planar NH3 has same structure.

Dear student
 
Based on VSEPR theory : Molecular shape of the PCl3 is Trigonal pyramidal and electronic geometry is teterahedral. Central phosphorous atom is sp3 hybridized and it has three bond pair and one lone pair of electrons.
 
The NH3 molecular geometry (molecular shape) is trigonal pyramidal. The NH3 bond angles are 107 degrees because the hydrogen atoms are repelled by the lone pair of electrons on the Nitrogen atom
