What are the different bond angles in a seesaw arrangement of atoms in a molecule?

The different bond angles are 120 degrees and 90 degrees. I believe he 90 degree angles are between the axial bond and the lone pair electrons.

To help with figuring out the bond angles, it helps to draw out the initial Lewis Structure of a given molecule. This structure indicates the amount of bonding regions about a central atom and thereby directs you to its relative molecular shape. Knowing the basic arrangement of the trigonal bipyramidal molecule helps you understand how these original angles will be affected by the presence of lone pairs.
