What are good books to study geometry for the IMO

366 Views Asked by At

I am looking to compete in the IMO, or at least in some other mathematical competitions. I read online that geometry is an important topic in many competitions, and so I'm looking for a book to self study.However most stuff I found so far was too basic (pythagorean theorem...) and so I'm interested in anything that covers more advanced topics or that has a lot of challenging practise problems.
