In this paper we show that the bisecants of an affinely regular n-gon inscribed in an ellipse of AG(2,q) cover all the points of AG(2,q) except the remaining points of the ellipse and possibly the center of the ellipse, if n≥√2q3/4. This completes the previous investigations of Korchmáros (1993) and Szonyi (1987), who studied hyperbolas and parabolas. The results can be used to construct various complete plane arcs using the method of Segre (1962) and Lombardo-Radice (1956). It is also shown how these results can be used to prove the completeness of particular k-arcs in spaces PG(n,q) of n dimensions that share k - 1 or k - 2 points with a normal rational curve. The best results are obtained by combining algebraic techniques with probabilistic ideas.
