On a fixed value theorem for directed areas of a kind of triangles in elliptic circumscribed polvgons
In this paper, a fixed value theorem for directed areas of a kind of triangles in elliptic circumscribed polygons is obtained, thus some results, including the famous Brianchon theorem for elliptic circumscribed triangles, are deduced easily.
