The “geometry problem” of the authors Delaunay and Zhitomirsky is not just a textbook, but a real find for everyone who seeks to deepen their knowledge in the field of geometry and develop logical thinking. This book will be a faithful companion for both schoolchildren and students, as well as for everyone who is interested in mathematics and wants to improve their problem solving skills. The Geometry Challenge contains a variety of problems covering a wide range of topics, from the foundations of geometric shapes and their properties to more complex concepts such as theorems and proofs. The authors carefully selected examples that will help readers not only to consolidate theoretical knowledge, but also to learn how to apply them in practice. Each task is accompanied by a detailed solution that allows the reader not only to see the final result, but also to understand the process of achieving it. This is especially important for those preparing for exams or Olympiads, where the ability to solve problems quickly and correctly plays a key role. The book will be interesting not only for schoolchildren, but also for teachers who are looking for high-quality materials for preparing lessons . It is suitable for those who are engaged in self-education, as well as parents who want to help their children in learning mathematics. If you are looking for effective ways to prepare for the exam or OGE, this tasker will be an excellent tool for training and increasing self-confidence. The topics raised in the book go beyond the simple study of geometry. The authors focus on the development of logical thinking and analytical skills, which makes the "Geometry Task Force" useful not only for studying mathematics, but also for forming a common approach to solving problems in life. Readers will be able to see how geometry permeates our daily lives, from architecture and design to natural phenomena. The style of the authors Delaunay and Zhitomirsky is distinguished by clarity and accessibility . They use simple and understandable explanations, which makes the material easy to perceive. This is especially important for readers who may have difficulty learning mathematics. In addition, the authors use interesting illustrations and diagrams, which helps to visualize complex concepts and makes the learning process more exciting. If you are interested in books such as "Geometry for Dummies" or "Mathematics. 1000 tasks”, then the “Geometry Tasker” will be a great addition to the library for you . This book will not only help you prepare for exams, but will also inspire further research in the world of mathematics. Reading this puzzle is not just about working with problems, it is an exciting journey into the world of logic and exact sciences. Do not miss the opportunity to make your path in the study of geometry more exciting and productive . The “Geometry Tasker” of Delaunay and Zhitomirsky is your reliable assistant on this path, which will help you not only understand, but also love mathematics.
