There are bright, distracting icons everywhere and the book is loaded with irrelevant color photographs of things like traffic signals, puppies, heroes on horseback, and the Statue of Liberty. Did you know that her index finger is 8 feet long? I do now, thanks to that book. But what this has to do with similar triangles I do not know.
I notice this in textbooks as well. It drives me crazy. But this may be partly a question of learning style, I think. I like a clear, linear flow of text and hate it when I can't tell what ot read first or when things go off-topic in little boxes. I HATE those DK books for the same reason, but plenty of people seem to adore them. I wonder if some of this is an adapatation for kids who are on the web all the time.
