In this post, we will see the book Problems in Geometry by P. S. Modenov.
About the book
This text offers certain general methods of solving problems in elementary geometry and is designed for teachers of mathematics in secondary schools and also for senior students.The present text includes material that goes beyond the scope of mathematics curricula for secondary schools (the use of complex numbers in plane geometry, inversion, pencils of circles and others).The book consists of five chapters. The first four chapters deal with the application of vector algebra, analytic geometry, complex numbers and the inversion transformation to geometric problems. Chapter V contains a list of the basic definitions and formulas used in the first four chapters. Before starting a new chapter, the reader is advised to refresh his memory with the appropriate material of Chapter V. Some of the derivations of formulas given in Chapter V are familiar to senior students of secondary school. More detailed theoretical material can be found in the bibliography at the end of the book.

Hello!
I need help.
Im imterested for some geoemtry books for university(dep.of mathematics) with full detailed solutions.
Can anyone help me? Thanks in advance 😊
