Ask HN: Help Identifying Geometry Book
2 by sanjayjc | 0 comments on Hacker News.
Hi HN, Years ago I came across, on this site, a math book by a Russian author that's just a carefully arranged sequence of geometry problems. Moreover, each problem is solely a picture with nary a word on the page. As I recall, the reader has to use previous results to solve subsequent problems. I can no longer find it in my bookmarks and I've searched online in vain. I no longer remember the title or author. Would someone on this site know the book I'm thinking of? Thanks Sanjay
