“Geometry” by Alexei Vasilyevich Pogorelov is not just a textbook, it is a real find for everyone who seeks to better understand the world of forms and spaces. Pogorelov, a well-known Russian mathematician and educator, offers readers a unique approach to the study of geometry, which combines both theoretical foundations and practical tasks. This book will become an indispensable assistant for students, schoolchildren and anyone interested in mathematics, regardless of their level of training. In Geometry, Pogorelov examines not only classical aspects, such as the properties of figures, theorems, and proofs, but also delves deeper into more complex topics, such as projective and differential geometry. The reader will be able to get acquainted with the basics of geometric analysis and modern methods that open new horizons in the understanding of spatial structures. Each section of the book is imbued with logic and clarity, which makes complex concepts accessible to perception. This book will be of interest to both students preparing for exams and students studying mathematics at a deeper level. It will also attract the attention of teachers who are looking for quality materials to prepare their lessons. Pogorelov creates an atmosphere of fascination with mathematics, inspiring readers to independent research and experiments. His style of presentation is clear and consistent, which makes it easy to digest even the most complex topics. The topics raised in "Geometry" cover a wide range of issues: from basic concepts about points, lines and planes to complex theorems and their applications in real life. Pogorelov not only teaches, but also makes you think about how geometry permeates our daily life. It shows how geometric principles are used in architecture, art, and even in nature. This makes the book not only a teaching tool, but also a source of inspiration for those who want to see the world from a new perspective. Pogorelov is the author of many works, among which one can distinguish "Elements of geometry" and "
