Projective Geometry and Line Geometry

This book is a contribution to visual geometry, mainly three-dimensional projective geometry and line geometry. There may be no better way to get deeply involved in spatial geometry than in exercising the skills of visual representation by the means of synthetic geometry. Thus I have adopted the synthetic method, which forms a characteristic feature of this presentation. In addition, I outline a special approach to Euclidean geometry: this ever present geometry is not conceived as a primitive sp ...
