+647 The first square in a sequence of squares is in ABCD position. (We read the vertices by starting with the lower-left vertex, and going clockwise.)
Then, after rotating it 90 degrees clockwise, it is in DABC position.
Next, it is reflected over a central vertical line, ending in CBAD position.
If the pattern of alternately rotating and reflecting continues, what position will the 2007th square be in? Give your answer with lower left vertex first and the other vertices in clockwise order.
