Construct a square PQRS such that lines PQ, QR, RS, and SP pass through given points A, B, C, and D respectively.

Discuss the configuration of the given points when the construction is not possible.

1.  Your OS back on track?

2.  Since you are talking about a square PQRS then I assumed that PQ, QR, RS and SP had to be line segments.  I was very much of that opinion at review, did that not come across then?
