A, a' .a''?

    A, a'.....a''?

    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!

    I don't think I'm completely understanding the question, but I would call the original ##A_0## and then derived ones as ##A_1, A_2## and so on. The next "angle group" would be the B's and then C's and so on.

    That makes sense. I've got a buddy who's a meth major and he said you can really name them whatever you want as long as they're labeled accordingly. I just didn't know if, since we use A and A' (A prime) if we could use A''(prime prime) and A'''(prime prime prime) I didn't know if there was a sort of "best practice" for this or not. Thanks for the input!

    Be careful. A 'meth' major could be a lot different from a 'math' major.

    As long as you are consistent and clear, do what you want.

    Be careful of conflicting notation, primes are commonly used to indicate differentiation. As long as you use it to mean only one thing you are fine.

    Lol so it could. Fortunately, even here in the meth capital of the world, he is the latter.

    That makes sense. I ended up really only needing A' and A'' so it didn't get too out of hand. The other angles were pretty insignificant. Thanks for the input everyone!
