The valence-shell electron-pair repulsion (VSEPR) theory states that electron pairs repel each other whether or not they are in bond pairs or in lone pairs. CH4 has no lone pairs of Electrons on the central atom so the optimal molecular shape would be tetrahedral with bond angels of 109.5. In NH3 and H2O there are 1 and 2 lone pairs, respectfully, so more repulsion exists between the bond and lone pairs, as a result, the bond angels are less than 109.5.
