Abstract: Abstract Geometry works, from ancient times, essentially with two instruments: a rule and a compass. The first one measures distances, the second, angles. Modern mathematics isolates these two activities in two subjects: metric spaces metric space (for a theory of distances) and inner product spaces inner product space (that presents a theory of angles or, if the reader prefers, orthogonality based in the notion of an inner product, also called a dot product dot product see{inner product} . Most interestingly, this notion—an inner product— is powerful enough to induce also a distance, and so the frame in which metric geometry can be done naturally is settled (see Sect. 11.1 ).
