A lone pair in the central atom

^ the lone pair on the central atom creates a repulsive force on the bonding pairs

Just to clarify, all three atom molecules are not bent. For example, BeCl2 has a linear shape with a bond angle of 180 degrees. The difference is in the lone pair of electrons. BeCl2 has no lone pairs around the central atom, where as something like H20 is not linear because of the exertion of force created by the two lone pairs atop the oxygen (central atom).
