I thought about it and it seems they can often be substituted for one another? Is this the case? When would you use each of them?
- He glared back at his brother, to which his brother told him to go out of the house with him.
- He glared back at his brother, after which his brother told him to go out of the house with him.
- He glared back at his brother, at which his brother told him to go out of the house with him.
Are these sentences interchangeable?

I had answered the question about this on the ELU site. I am taking the liberty of reposting my answer here:
The trick to knowing how to use; of which, at which, in which, to which, from which (etc.) is to analyse the prepositional phrases, phrasal verbs, verbs and prepositions in a sentence and then see how it can be transformed:
Summary (and not a complete answer but a general one): The preposition depends on the verb that takes a preposition, a phrasal verb that includes a preposition, or it depends on the prepositional phrase used. Also, there are many other prepositions that can be paired with which: under, during, about, over, etc.
