CHAN'S PROBLEM

Chan's Problem is an elementary problem in combinatorial geometry. It is stated thusly:

[math] \begin{displaymath} \xymatrix{ \circ & & \circ \\ & \circ & } \end{displath} [/math]

Given the drawing above and using exactly three lines, find a way to partition each vertex so that it lies within a face with no other vertex.
