INTRODUCTION

This book presents the main results of Euclidean geometry, declined in the form of plane geometry and solid geometry.

Like arithmetic and algebra, geometry represents one of the cornerstones of mathematical knowledge, necessary not only for understanding any sector of this discipline (analytical geometry, trigonometry, mathematical and functional analysis), but above all for solving concrete problems related to every aspect of science and human life.

Precisely because of the importance of geometry, the majority of the results presented in this manual were already known in antiquity, especially among the Greeks.

Each chapter will be accompanied by some final exercise. This manual is not a workbook and, precisely for this reason, you will not find hundreds of exercises.

The questions proposed were considered significant for understanding the main rules and for their application.

In addition, particular emphasis has been given to the method of solving them since the real leap in quality between the study of a rule and its application is given precisely by the method, i.e. by the quality of the reasoning, and not by the quantity of calculations.

The program presented in this manual expands what is taught in technical institutes and high schools, generally in the first two years, for the exposure of non-Euclidean geometries, usually omitted in the programmes.
