While it was the subject of a struggle, the problem of the parallels seemed an intractable monster, devouring egos, relationships, and careers, threatening to destabilize mathe

Paul Sellnick,Ernst Heimard Cludiusulate. There are two possibilities: the Euclidean case, where every triangle is Euclidean, and the hyperbolic case, where every triangle has a positive angular defect. In this chapter, we consider properties of the plane in the latter case.

Second, affine geometry is based on linear algebra, which is fundamental in applications and in mathematics more generally. An introduction to affine geometry thus gives us an excuse to profer a qu
