In situations where there are two bond angles such as 120 and 90 in molecular shapes such as trigonal bipyramidal, how would you know what bond has the 120/90 degree when labeling?

The angles to the bonds are shown in the textbook. You can draw out the VSEPR model to see approximately what the angles are. Other than that you may need to memorize them. The angles will be the maximum space apart that the atoms can move to. This is due to the repulsion of the lone pairs.
