**Steve**, Friday, December 30, 2011 at 4:31pmAs it stands now, A and D are on the same horizontal line, and B and C are on the same horizontal line.

However, we want to move only point B. So, if we keep BC parallel to AD, then we want to have BC the same length as AD, which is 6.

Right now, the length of BC is 5-1 = 4. So, to increase the length to 6, staying on the line y=5, we move B to (-1,5).

Now we have two parallel sides, AD and BC of length 6. Note also that now AB and CD are parallel and the same length, so we have a parallelogram.
