In short, I believe you when you say you haven't used any THING that you learned in geometry. But I'm also a bit skeptical that nothing you got out of geometry was even indirectly useful in support of other study.
I can't remember what geometry was about.
I just know that I had to take it to take the upper level algebras.
Whatever I do, I generally do automatically. I normally can't show my work because I can't tell you what I did. I just know that the answer is accurate because it feels accurate.
This is why I *loved* math multiple choice tests. All I needed to do was pick the right answer, and it was generally obvious.
So, teaching is not an ideal profession for me.
