You need to use VSEPR theory to determine the shape of a molecule. There are many planar molecules.

A molecule with 3 bond pairs and 0 lone pairs has equal repulsion by all three bond pairs, causing a trigonal planar shape, with a bond angle of 120 degrees, eg:

A molecule with 4 bond pairs and 2 lone pairs has equal repulsion from the two lone pairs of electrons, causing a square planar shape with a bond angle of90 degrees, eg:
