Geometry Geometry this very ancient field of study of mathematics frequently remains too little familiar to students. Michèle Audin professor at the University of Strasbourg has written a book allowing them to remedy this situation and starting from linear algebra extend their knowledge of affine Euclidean and projective geometry conic sections and quadrics curves and surfaces. It includes many nice theorems like the nine point circle Feuerbachs theorem and so on. Everything is presented clearly and rigourously. Each property is proved examples and exercises illustrate the course content perfectly. Precise hints for most of the exercises are provided at the end of the book. This very comprehensive text is addressed to students at upper undergraduate and Masters level to discover geometry and deepen their knowledge and understanding
