I figured if I was going to try using the Painless Algebra book, I should try the Painless Geometry book.
Published: my edition in 2009; latest edition in 2009
Genre: math textbook
Length: 311 pages
Summary: This book provides an introduction to geometry. It covers all the basics, including angles, parallel and perpendicular lines, triangles, quadrilaterals, circles, perimeter, area, volumes, and graphing. For each section, a concept is introduced and then an example is worked through. Formulas and common mistakes are set apart from the regular text. Each section includes around five questions to practice, with the answers provided at the end of the chapter, and often a geometry experiment to emphasize the material learned in that section.
Final thoughts: Again, this is a nice review of geometry or a basic introduction, but you wouldn’t want to have this be your sole geometry textbook. There isn’t nearly enough practice for the student, and while it discusses theorums, it doesn’t go into proofs at all. It’s got silly drawings throughout the book and doesn’t look like a textbook, so it fits the painless part of the math. However, I recommend using it in addition to another geometry book or as a refresher.
Title comes from: It’s part of the Painless series of books that purport to teach you math in a pain-free manner.
