What kind of geometry topics will be needed to succeed in trig?

Okay so it's been a really long time since I've taken geometry. Maybe like 3 years while I was in high school. I signed up for trig next semester. I am in college. I am excellent at algebra and was really good at geometry too, it's just I've forgotten it since its been a while. With a review ill refresh and it will come back to me.

My question is: what kind of topics should I review over the summer to be able to succeed and get an A in trig?

Although I only did basic trig, it took little GEOMETRY knowledge, just trig itself. It didn't require any geometry terms for me, only math and formulas.
