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.
