## CabriJava demonstration of Pappus's Theorem |

Pappus's Theorem states that, if alternate vertices of a hexagon (AB'CA'BC' in the figure) are collinear, Then the intersections of opposite sides (P, Q and R in the figure) are collinear. |

You may move any of the points A,B,C,A',B',C', *on their lines*

or either of the lines ABC or A'B'C' by clicking
on them and dragging them to a new position

You will see that P, Q and R remain collinear.
