Three Tangents, Three Chords in Ellipse
The applet below offers an illustration to a statement which is a particular case of Pascal's Hexagon Theorem: given a triangle T1T2T3 inscribed in a non-degenerate conic. Let t1, t2, t3 be the tangents to the connic at points T1, T2, T3. Then the points of intersection of TiTj with tk

How does Pascal's theorem apply? Let the vertices of an inscribed hexagon coalesce in adjacent pairs producing a triangle with three sides of the hexagon degenerating into the tangents at the vertices of the so obtained triangle.
