Head First 2D Geometry

Praise for other Head First books

“Head First Algebra is a clear, easy-to-understand method to learn a subject that many people find

intimidating. Because of its somewhat irreverent attitude in presenting mathematical topics for

beginners, this book inspires students to learn Algebra at a depth they might have otherwise thought

unachievable.”

— Ariana Anderson

Statistician at UCLA’s Center for Cognitive Neuroscience

“The way Head First Algebra presents information is so conversational and intriguing it helps in the

learning process. It truly feels like you’re having a conversation with the author.”

— Amanda Borcky

College student

“Head First Algebra has got to be the best book out there for learning basic algebra. It’s genuinely

entertaining.”

— Dawn Griffiths

Author, Head First Statistics

“Head First Algebra is an engaging read. The book does a fantastic job of explaining concepts and taking

the reader step-by-step through solving problems. The problems were challenging and applicable to

everyday life.”

— Shannon Stewart

Math teacher

“Head First Algebra is driven by excellent examples from the world in which students live. No trains leaving

from the same station at the same time moving in opposite directions. The authors anticipate well the

questions that arise in students’ minds and answer them in a timely manner. A very readable look at the

topics encountered in Algebra 1.”

— Herbert Tracey

Instructor of mathematical sciences, Loyola University Maryland

“If you want to learn some physics, but you think it’s too difficult, buy Head First Physics! It will probably

help, and if it doesn’t, you can always use it as a doorstop or hamster bedding or something. I wish I had

a copy of this book when I was teaching physics.”

— John Allister

Physics teacher

Praise for other Head First books

“Head First Physics has achieved the impossible—a serious textbook that makes physics fun. Students all

over will be thinking like a physicist!”

— Georgia Gale Grant

Freelance science writer, communicator, and broadcaster

“Great graphics, clear explanations, and some crazy real-world problems to solve! Head First Physics is full of

strategies and tips to attack problems. It encourages a team approach that’s so essential in today’s work world.”

— Diane Jaquith

High school physics, chemistry, and physical science teacher

“Head First Physics is an outstandingly good teacher masquerading as a physics book! You never feel fazed

if you don’t quite understand something the first time because you know it will be explained again in a

different way and then repeated and reinforced.”

— Marion Long

Teacher

“Dawn Griffiths has split some very complicated concepts into much smaller, less frightening bits of stuff

that real-life people will find very easy to digest. Head First Statistics has lots of graphics and photos that

make the material very approachable, and I have developed quite a crush on the attractive lady model

who is asking about gumballs on page 458.”

— Bruce Frey

Author, Statistics Hacks

“Head First Statistics is an intuitive way to understand statistics using simple, real-life examples that make

learning fun and natural.”

— Michael Prerau

Computational neuroscientist and statistics instructor, Boston University

“Thought Head First was just for computer nerds? Try the brain-friendly way with Head First Statistics and

you’ll change your mind. It really works.”

— Andy Parker

“Down with dull statistics books! Even my cat liked Head First Statistics.”

— Cary Collett

Wouldn’t it be dreamy if

there was a book to help me

understand geometry that was

more fun than going to the

dentist? It’s probably nothing

but a fantasy....
