im in the process of typing out an idea I had about triangles, and I wanted some input, but I ran into a problem when I realized I do not know how to denote multiple "prime" angles. In this diagram, I am working with the corners of a triangle, but have extended the rays outwards throught thier intersection so they form 4 angles including the angle from the triangle. The angle from the triangle I am calling A, but I want to sort of lump them all together, so can I call the other three A', A'', and A'''?

I have never been in a situation where this notation was neccesary so I had no idea how to label it.

thanks in advance!
