In the Lewis structure of these molecules, the central atom(s) bonds with only two other atoms and has no unshared electrons. Only two electron clouds emerge from that central atom. For these two clouds to be as far away from each other as possible, they must be on opposite sides of the central atom, forming a bond angle of 180° with each other. An angle of 180° gives a straight line. The VSEPR theory says, then, that the geometry around an atom that has only two bonds and no unshared electrons is a straight line.
