I'm not even sure I know what a geometric proof is, so I'd say no? Our teacher would just ask us to solve this sort of exercises with a compass and a ruler, and then he'd grade the tests by checking whether the process to reach the solution made sense (i.e.: I'm pretty sure that level 20 was one of the questions in my midterms). He would have explained the resolutions for most of them in previous lectures, but others were new to us. I can't remember if an additional written proof was required.
