TITLE: Book recommendation on plane Euclidean geometry
QUESTION [46 upvotes]: I consider myself relatively good at math, though I don't know it at a high level (yet). One of my problems is that I'm not very comfortable with geometry, unlike algebra, or to restate, I'm much more comfortable with algebra than geometry. I think that's mainly because my geometry education was sparse through the years, lacking in consistency etc. So I'd like to revise (and learn more) all at once, catching the basic axioms, understanding why such is such, etc. Essentially, a moderately rigorous textbook in plain Euclidean geometry (nothing fancy). Please don't say "The Elements" - I have browsed it at the bookstore, it is quite good, but not really what I'm looking for right now.

REPLY [2 votes]: “A Beautiful Journey Through Olympiad Geometry” is a book that presents all the theorems/methods that you need to know in order to solve Olympiad geometry problems. It progresses step-by step, starting from scratch, so you will definitely be able to follow it without any additional materials. It contains solved problems using these theorems, but also related problems that are left unsolved as a practice for the reader. Check out the book preview and download the book (pay what you want) here.
