Bond angle can also be defined as the geometric angle between any two adjacent covalent bonds. This bond tells us about the molecular geometry of the compound.Complete answer: The bond angle generally depends on the number of lone pairs present in an atom. An atom which has no lone pairs shows a shape of trigonal planar shape and in this case bond angle is of $120{}^\circ$. The molecule which contains one lone pair which forms a bent shape and bond angle is of $118{}^\circ$. On the other hand if a molecule has two lone pairs then it forms a linear shape. For example a compound known as methane which has no lone pairs forms a tetrahedron showing bond angle of $109.5{}^\circ $, ammonia has one lone pair have bond angle of $107.5{}^\circ$ and forms trigonal pyramidal shape whereas water having two lone pairs of electrons has a bent shape with bond angle of $104.5{}^\circ $.VSEPR theory is basically used to predict the geometry of molecules; this theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. Hence in this way we can calculate the bond angle of any moleculeNote: Mainly VSEPR theory tells us about the bonding and molecular geometry of organic molecules and polyatomic ions. It predicts the 3-D shape of the molecule and it can predict the shape of nearly all compounds.
