(Polar molecules, Non-polar molecules, etc.)

Geometry refers to the arrangement of elections, including both bond and lone pair electrons. On the other hand, shape only refers to the bond electrons. For example, NH3 (ammonia) has 4 regions of electron density (1 lone pair and 3 [single] bonds [to the hydrogens]). The geometry of ammonia would be tetrahedral but the shape (which does not include the lone pair) would be trigonal pyramidal.
When no lone pairs of electrons are present, the electronic geometry is the same as the molecular shape. Things are different when a lone pair is presented. Different molecules with the same geometry shape can have different molecular shapes depend on the number of their lone pairs.
