If we’re just talking math, triangles can be defined in terms of 3-element subsets of all 3 (A)ngles and 3 (S)ides:
SSS - unique
SAS - unique
ASS - may be unique depending on the lengths of the sides
ASA - unique
SAA - unique
AAA - infinite solutions
Maybe someone cleverer than me can figure out how that maps on to love and gender.
I pulled this same thing in college. I was a CS major in the late 90’s and I took a class from the writing department on changing discourse in a new digital era.
The professor was really good at literary analysis and knew next to nothing about computers. He was spot on that big changes were afoot but he was as wrong as anyone else on what those changes were (spoiler: we all thought we would have an alternate universe in Cyberspace TM).
We had the option of creating a website as our final project and we realized that if we just put in every possible feature we’d get an A. Animated backgrounds? Moving fonts? Music? A goofy mouse pointer? No feature was too dumb. If it was something you couldn’t do on a piece of paper, we added it to our website.
We got our A. It was a dirty A but we took it.
