Proving Lines Contain Exactly n Points in an Affine Plane of Order n

In summary, an affine plane of order n is a n-dimensional Euclidean space with an orthonormal system consisting of n mutually orthogonal unit vectors. The algebra of general affine tensors is developed by abstracting from this space. Each line in this affine plane contains exactly n points, which can be obtained through a linear transformation and satisfying an orthogonality condition.

Hi, I will try to help you out :)

Lets consider an n-dimensional Euclidean space [tex]E_{n}[/tex] and by means of abstraction we develop the algebra of general affine tensors.

An orthonormal system [tex] e_{j} [/tex] in [tex] E_{n}[/tex] consists of n mutually orthogonal unit vectors. Any orthonormal system [tex] {\bar{e}_{j}} [/tex] may be obtained from the first by means of the linear transformation

[tex] \bar{e}_{j} = \sum^{n}_{h= 1} a_{ j, h} e_{h} (j = 1, ..., n) [/tex]

provided that the coefficients [tex] a_{jh}[/tex] satisfy the orthogonality condition

[tex]\delta _{j,k} = \sum^{n}_{h=1} a_{j,h} a_{k, h} (j, k = 1, ...,n), [/tex]
