Query: Riddled with Errors!

I was disappointed as I worked through the first two chapters of this book. It is simply riddled with errors. At first, I thought it was just me, but as the errors become more and more blatant, I realized that it was the book and not my inability as a student. One example problem (from Page 44) "Triangle CDE is congruent to Triangle C'D'E'. If angle D=48 degrees and angle E = 17 degrees, find the measure of angle F." It turns out that there would be no angle F in that triangle! If there were just one or two errors in the book, I could let it go, but I've found one such error on almost every page! I'm giving up on this book. It seems like it would have been a good text, but the abundance of errors makes it pretty much useless.Save your money and don't buy this book. I got the now out of print "Geometry & Trigonometry for Calculus" by Peter Selby, so I'm going to try that next.
