Having trouble with geometry? Do Pi, The Pythagorean Theorem, and angle calculations just make your head spin? Relax. With Head First 2D Geometry, you'll master everything from triangles, quads and polygons to the time-saving secrets of similar and congruent angles -- and it'll be quick, painless, and fun.
Through entertaining stories and practical examples from the world around you, this book takes you beyond boring problems. You'll actually use what you learn to make real-life decisions, like using angles and parallel lines to crack a mysterious CSI case. Put geometry to work for you, and nail your class exams along the way.
We think your time is too valuable to waste struggling with new concepts. Using the latest research in cognitive science and learning theory to craft a multi-sensory learning experience, Head First 2D Geometry uses a visually-rich format designed for the way your brain works, not a text-heavy approach that puts you to sleep.
Lindsey Fallow has spent the past decade exploring science and technology as a writer, software developer, and television personality. Following an undergraduate degree in Manufacturing Engineering, she fronted a science show for 8-12 year-olds on Disney, and went on to become a reporter & Associate Producer for Tomorrow's World (the BBC's #1 prime-time UK science and technology show) from 1998-2002. She's stood on the top of the Golden Gate bridge, fed sharks, filmed brain surgery, flown in military planes, and been bitten by a baby tiger, but is the most excited by far when her 13-year-old stepson 'gets' his homework.
Dawn Griffiths started life as a mathematician at a top UK university. She was awarded a First-Class Honours degree in Mathematics, and was offered a university scholarship to undertake a PhD studying particularly rare breeds of differential equations. She moved away from academia when she realized that people would stop talking to her at parties, and went on to pursue a career in software development instead. She currently combines IT consultancy with writing and mathematics.
When Dawn's not working on Head First books, you'll find her honing her Tai Chi skills, making bobbin lace or cooking nice meals. She hasn't yet mastered the art of doing all three at the same time.
She also enjoys traveling, and spending time with her lovely husband, David.
Comments about O'Reilly Media Head First 2D Geometry:
Chapters 1 and 2 were well written and did not skip any steps. The small callouts and arrows were helpful and needed. However, by Chapter 3, the tone changed and important things like knowing how to calculate a square root and learning the concept (and performing an activity) stated by the second bullet point on page 138 of Chapter 3 were missing. This is a big oversight. The only activity in Chapter 3 uses a magnet set and doesn't explain the answers of problems well at all. If this was the work of the second author, it was not as good as the first two chapters, which more clearly follow the "Head First" way of explaining things. How about re-writing Chapter 3?
