 Van Bendegem (1987) argued that in a finite geometry it should be a basic fact that lines and points have extensions. In particular, lines are supposed to have a constant width (independent of the orientation of the line) \(N_{D}\) Thus \(N_{D}\) represents a large (finite) number, corresponding to the number of squares that form \(N_{D}\). Given a line, the width is always defined as perpendicular to that line. Now suppose that the line has an orientation corresponding to an angle \(\alpha\) between the line and the \(x\)-axis. Then the width \(N_{D}\) of that line, when projected on the \(x\)-axis will be \(\left[\frac{N_{D}}{\sin \alpha}\right]\) where the expression \([x]\) indicates the greatest integer less than or equal to \(x\).
