Review: A great free geometry book
Rating: 5 out of 5

The ck12.org foundation has made more than a dozen free math and science textbooks available, and this geometry textbook is one of them.There are full images in this.  This book is much larger than what is typically available for free.  The images look good, but they are typically roughly two times too large at the moment.  Also, all places where TeX is used, a too-large blocky image is used instead.  For example, "(3,3)" is presented three times larger than the surrounding text.  There are many of these on every page, but at least it's consistent.I noticed several spelling mistakes.  Since this is a digital textbook, I'm sure those will be fixed.  The errors above will also probably be addressed quickly.This is worthwhile download.  The PDF version is 918 pages, so this is a big book.
