Utterly Confused About Molecular Geometry

We will examine the geometries of the two Lewis structures derived in Section 9-7. 

If we examine the other central atom, the oxygen with the attached hydrogen, we observe the presence of two lone pairs and two bonds. The presence of these pairs and bonds, which total four, means that the electron-group geometry is tetrahedral. This arrangement has sp3 4 5 6 hybridization. Since there are two lone pairs, the molecular geometry is bent. 

Determine the molecular geometries about the central atom for each of the following.
