I am writing a paper about a geometric algorithm where one of the main operations is dividing a rectangles to two smaller rectangles. It is important that there are two pieces, and that the pieces don't have to be equal. I am looking for a single verb that I can use in this context.
There are many English words that are specific to the number 2, for example "couple" (a group of 2), "half" (one of 2 equal parts), "both", etc. So, I thought there may be a word specific for dividing to two parts
I thought of bisecting, but according to Meriam-Webster it means "two equal parts".
Bipartite seems like a good candidate, but according to Meriam-Webster it is an adjective, and I need a verb.
I asked in ell and got many answers (splitting, cleaving, dividing, separating, breaking), but none of these imply that there are exactly 2 pieces.
EDIT: In the future I may change the algorithm to cut into 3 parts, so, it could be good to have a verb that can be naturally modified to indicate 3 parts.
