The book "A new problem solver in geometry" by Jacob Perelman is not just a textbook, but a real guide to the world of geometry, which will help readers not only to master the theoretical foundations, but also to develop logical thinking and creative approach to solving problems. Jacob Perelman, known for his fascinating and accessible explanations of complex mathematical concepts, created this puzzler to make the study of geometry an interesting and fascinating process. The "New Problem Book on Geometry" contains problems of varying complexity, which cover all key topics of geometry: from simple figures to complex spatial bodies. Each task is accompanied by detailed solutions and comments, which allows the reader not only to find the right answers, but also to understand how and why they are obtained. This makes the book ideal for schoolchildren, students and anyone who wants to deepen their knowledge in mathematics. The book will be especially useful for high school students preparing for exams, as well as students studying mathematics at a deeper level. Teachers and tutors will also find in it a lot of useful materials for preparing lessons and individual classes. Thanks to the available language and logical construction of tasks, the "New Geometry Task Force" will be an excellent assistant for all who strive for success in their studies. The topics raised in the book go beyond simple geometry. Perelman addresses questions of logic, spatial thinking, and even the philosophy of mathematics. It shows how geometry permeates our daily lives, how it helps in architecture, art, and even in nature. Readers will be able to see how geometric principles are applied in the real world, which will make the study more meaningful and fascinating. The style of Jacob Perelman is easily recognizable - it combines the depth of thought and simplicity of presentation. His other well-known works, such as "Tasks and Exercises in Mathematics" and "Physics for Lovers", also feature a bright and accessible style that makes complex concepts understandable to a wide audience. Perelman skillfully uses life examples and fascinating stories to make the material more lively and memorable. The New Geometry Task Force is not just a book, but an entire world into which the reader can immerse himself while exploring the infinite possibilities of geometry. It will become a faithful companion for everyone who wants not only to solve problems, but also to understand how mathematics itself works. Readers interested in topics such as logic, spatial thinking, and mathematical modeling will find many useful ideas and solutions in this book. If you are looking for where to find interesting problems in geometry, or want to improve your skills in mathematics, the "New Geometry Tasker" will be an excellent choice. This book will not only help you prepare for exams, but will also open new horizons in understanding geometry and mathematics in general. Do not miss the opportunity to get acquainted with this fascinating work and immerse yourself in the world of numbers and figures that awaits you in the pages of the book by Jacob Perelman.
