- Advance Praise for Head First 2D Geometry; Praise for other Head First books; Copyright; Dedication; The Authors; Table of Contents; How to Use this Book: Intro; Who is this book for?; We know what you're thinking.; And we know what your brain is thinking.; Metacognition: thinking about thinking; Here's what WE did:; Read Me; The technical review team; Acknowledgments; Safari® Books Online; Chapter 1: Finding Missing Angles: Reading Between the Lines; There's been a homicide; In the ballistics lab you've got to cover all the angles; Do the angles between Benny, Micky, and the bullet match up?
- Right angles aren't always marked with numbersAngles can be made up of other, smaller angles; Complementary angles always add up to a right angle (90o); Right angles often come in pairs; Angles on a straight line add up to 180o; Pairs of angles that add up to 180o are called supplementary angles; Vertical angles are always equal; The corner angles of a triangle always add up to a straight line; Find one more angle to crack the case; Something doesn't add up!; If it doesn't all add up, then something isn't as it seems; You've proved that Benny couldn't have shot Micky!
- We've got a new sketch-now for a new ballistics reportWe need a new theory; Work out what you need to know; Tick marks indicate equal angles; Use what you know to find what you don't know; The angles of a four-sided shape add up to 360o; Parallel lines are lines at exactly the same angle; Parallel lines often come with helpful angle shortcuts; Great work-you cracked the case!; Your Geometry Toolbox; Chapter 2: Similarity and Congruence: Shrink to Fit; Welcome to myPod! You're hired; Liz wants you to etch her phone; The designer noted some of the details
- The design tells us that some triangles are repeatedSimilar triangles don't just look the same; To use similarity, you need to be able to spot it; You can spot similar triangles based on just two angles; Employee of the month already?; You sketch it-we'll etch it!; Fire up the etcher!; The boss isn't happy, but at least you're not fired...; It's a problem of scale...; Complex shapes can be similar, too; You sketch it-we'll etch it (to fit); Liz is back with a special request; Similar shapes that are the same size are congruent; Use what you know to find what you don't know
- Ratios can be more useful than sizesRatios need to be consistent; Your new design ROCKS!; Your Geometry Toolbox; Chapter 3: The Pythagorean Theorem: All the Right Angles; Giant construction-kit skate ramps; Standard-sized-quick-assembly-what?!?; The ramps must have perpendicular uprights; You can use accurate construction to test ramp designs on paper; Not all lengths make a right triangle; You can explore a geometry problem in different ways; In geometry, the rules are the rules; Any good jump has some similar scaled cousins; The lengths of the sides are linked by a pattern
