What are cis and trans alternate types of? I don’t think it’s “gender identity” because wouldn’t that just be man, woman or nonbinary regardless of whether they’re cis or trans? Cis/trans just being a qualifier?
If the answer is “I am cis” or “I am trans”, what is the question?
Edit: Someone came up with the term “gender congruity” and (after looking up the definition of “congruity”) I think this describes what I’m talking about perfectly.
I’m a little confused as to why you’d say there’s no such category.
Maybe “correspondence between” would be a better term?
Cisgender means that at birth your doctor said “this baby is H gender” and you now currently say “I am H gender”.
Transgender means that at birth your doctor said “this baby is H gender” and you now currently say “I am not H gender”.
The terms refer to the relationship between the gender the doctor assigned you at birth and what your actual gender is.
