Elemente der Geometrie

The book is aimed at students in teacher training programs at all school levels, as well as educators in the field of mathematics. It includes the scientific background of geometry in current mathematics instruction, including computational methods, but also touches on numerous related topics such as the geometry of complex numbers, spherical trigonometry, graph theory, finite geometries, and models of non-Euclidean geometries. Numerous application examples and about 300 exercises with solutions make the book an effective working resource. The present 5th edition has been completely revised. The content has expanded the topic of band ornaments, and the subject of projective geometry has been newly included. Voice on the book: "A versatile book that addresses all facets of elementary geometry and shows connections. Suitable for broadening horizons.".
