Euclidean Geometry: A Guided Inquiry Approach (MSRI Mathematical Circles Library)
An interesting and singular approach of the Euclidean geometry is contained in this book . . . [The] book covers all the topics listed in the common core state standards for high school synthetic geometry . . . [T]he didactical approach of the large collection of problems, solutions and geometrical constructions is very important to consider it as a good textbook for teaching and learning synthetic geometry. --Mauro Garcia Pupo, Zentralblatt MATH
