The orientation of ABCD is clockwise, while that of GHIJ is counterclockwise. This means an odd number of reflections will be involved.
If we work backward from the second selection list, we see that segment AB needs to map to a position 15, 20, or 25 units above where GH lies. At 20 units above GH, it is in line with point A (not B) as a center of rotation.
If GH is translated up 20 units, then reflected across the y-axis, point G becomes coincident with A, and point H becomes rotated 90° CCW about A from B's location.
We conclude the transformations required are
• 90-degree counterclockwise rotation about point A
• reflection across the y-axis and a translation 20 units down
