Kim Yong-un et al.: Fun School Trip 3: The World of Geometry (30th Anniversary Edition)

This is the 30th anniversary edition (revised edition) of *A Fun Math Journey* (4 volumes), which opened a new chapter in popular mathematics books by immersing countless readers in a magical world of mathematics. The content has been reviewed and proofread once, and the text and cover design have been updated. Volume 3 contains geometric problems that can be pondered in an enjoyable way, like solving a puzzle, along with the thought processes involved in solving them. Starting with the practical geometry of Egypt and the theoretical geometry of Greece that emerged in the early stages of human civilization, the book explores geometric problems hidden within history and everyday life. Why is the inclination of a pyramid 51 degrees? Why is the volume of a cone one-third that of a cylinder? Can an angle be trisected using only a ruler and a compass? What geometric principles are hidden within the riddle of a matchstick? Also, why are beehives hexagonal? Is there no way to escape any maze? This is a substantial book that allows readers to comprehensively learn the essential geometric concepts needed to answer these questions, starting from the basics, accompanied by intuitive illustrations.
