[Math] What do Greek Mathematicians use when they use our equivalent Greek letters in formulas and equations

math-historynotation

Like for example, it's common to use the Greek letter $\theta$ to represent an angle right? So what would a Greek person doing math use to represent an angle? Would they also use $\theta$? Or is there another notation that they would use in order for them to use their letters like we do? Such as if we say $A\geq B$, would a Greek student, mathematician, or whoever say: $\alpha \geq \beta$ or is there something else they say? It just seems like the Greek letters from a non-Greek point of view have so much meaning to us, but then how do they percieve their letters used in mathematics?

The Greeks seems to use the Latin letters together with Greek letters as the rest of us. Here is a screen dump from some notes on Functional analysis. Of course this is just an example. enter image description here
