[Math] Math symbol that means “associated”

notation

I am looking for a Math symbol that means "associated" and I don't mean "associated" as something as complicated as isomorphism or anything super fancy.

I am looking for a symbol that means something like "$\triangle ABC$ [insert symbol] $A_{1}$" (as in triangle ABC "associated" with area_{1}) Or want to say something like "The eigenvector associated with the eigenvalue"

You get the idea.

If you want to use such a symbol for association in some sense, you would have to define its meaning precisely first in your exposition. I suggest using $\sim$ for your purpose.
