So I'm finishing highschool in my country and at the end we have to do this 'sort of' graduation thesis, but it's not as serious as in university. I took Math for my subject and I got this "Appliance of triangle homotethy", hope I translated it right. Well I have written about 9 pages explaining homotethy and triangle homotethy basics and the paper needs to be 15 pages at least and I don't know of which appliances to talk about, I googled it but didn't find anything to help me. I don't know with what to continue, what specific appliances? Thank you in advance.
