Geometry Explorer

"You can trick yourself into creating something so grand that you would never have dared to plan such a thing."

Version 2

I've decided to re-write the book for various reasons. Here is a preview that consists of the first four chapters, which all span the first part.

Unsurprisingly, expect many errors. If you find them, please email me or PM me on AoPS at dchenmathcounts.

(Version 1 is listed in "Handouts" for posterity.)


I also have a math program that I teach online. My recommendations for math contests are here.

About Me

I like to run track, eat snacks, do math, and live fast. I enjoy watching anime, reading manga, reading books, and in my spare time I like to write fiction and play various games. You can find my reviews here.
