描述This textbook teaches the transformations of plane Euclidean geometry through problems, offering a transformation-based perspective on problems that have appeared in recent years at mathematics competitions around the globe, as well as on some classical examples and theorems. It is based on the combined teaching experience of the authors (coaches of several Mathematical Olympiad teams in Brazil, Romania and the USA) and  presents comprehensive theoretical discussions of isometries, homotheties and spiral similarities, and inversions, all illustrated by examples and followed by myriad problems left for the reader to solve. These problems were carefully selected and arranged to introduce students to the topics by gradually moving from basic to expert level. Most of them have appeared in competitions such as Mathematical Olympiads or in mathematical journals aimed at an audience interested in mathematics competitions, while some are fundamental facts of mathematics discussed in the framework of geometric transformations. The book offers a global view of the geometric content of today‘s mathematics competitions, bringing many new methods and ideas to the attention of the public..Talent

Economics, Government and SocietyOur discussion begins with those transformations that lie at the heart of the notion of equality in geometry. We tend to identify two geometric figures and call them . (or . when we are very rigorous) if we can place one on top of the other to coincide exactly.

Econometric Analysis of Carbon MarketsThis chapter is devoted to transformations that dilate or shrink geometric objects by a fixed factor. Such transformations occur naturally in real life, for example, when changing scale, with or without rotation.
