What is the reference point for edges angle display?

When I display angles for edges these are always 90°, I am wondering what is the reference calculation object of a single edge angle display and how to change it?

PS: I know I can see the angles when selecting a face, however what is the meaning to have these 90° displayed then and can I change it?
