Question 1208063
<pre>

But after thinking about it some more, it is necessary to prove QR is parallel
to AP, for if QR and AP weren't parallel, then triangles RQC and ABC would not be
similar. So while it wouldn't matter to get the area of triangle ABQ equal to the
area of quadrilateral PBQR, it is absolutely necessary to determine the area of
triangle AQC.  We'll see what Ikleyn can do about proving them parallel. I now
think it's necessary.
