I am reading the book, "Lemmas in Olympiad Geometry".This book has a nice collection of problems at the end of almost every chapter but unfortunately, there is no solution given to it. Now I am helplessly trying to solve these problems but unable to solve many of them. Even if I ask for a solution in MSE, It is getting downvotes.
Let alone solving those problems, I am unable to make any approach to some of those. How can I get hints or solutions to these problems?
