Abstract: Abstract Affine real spaces can be provided with an additional “scalar product”, which yields corresponding notions of distance, angle, perpendicularity. And of course various additional geometric notions can now be studied: squares, rectangles, rotations, orthogonal projections, and so on. In particular, the theory of orthogonal projections provides many interesting applications in approximation problems: approximation by the law of least squares, Fourier approximation, and so on.
