Type of molecule	Shape
A) ${\text{AB}}_{\text{3}}$	1) Angular
B) ${\text{AB}}_{\text{3}}\text{E}$	2) Trigonal pyramidal
C) ${\text{AB}}_{\text{3}}{\text{E}}_{\text{2}}$	3) Trigonal planar

In ${\text{AB}}_{\text{3}}$ type of molecule, central atom has 3 bond pairs and no lone pairs.

The shape of  ${\text{AB}}_{\text{3}}$ is Trigonal planar. ${\text{AB}}_{\text{3}}\text{E}$ type of molecule has total 3 bond pairs and 1 lone pair around the central atom.  Hence, the molecular geometry is Trigonal pyramidal. ${\text{AB}}_{\text{3}}{\text{E}}_{\text{2}}$ type of molecule has 3 bond pairs and 2 lone pairs around the central atom. Therefore, the geometry of molecule is ‘T shape or Angular’.
