Nice motivator, Holt.

Right Triangle Dog

The Holt Geometry book starts every section with some “real world” application of the topic.

Its a bad book.

EDIT: I’ll revise my comments from earlier this year.  Its an OK book.  In writing classes a common piece of advice is “show, don’t tell.”  The Holt Geometry book, along with many others, fail in this regard.  It does nothing for a student to read in chapter 1 that a^2+b^2=c^2.  The Pythagorean theorem is a result of a long logical flow of geometric arguments.  (and still, the inane “Who uses this?” motivators make me want to defenestrate somebody) -2010.05.04
