Aircraft X was being vectored from the east downwind to Runway 35R for an ILS approach descending 8;000 feet. Aircraft Y was being vectored from the west downwind for an ILS approach to Runway 35R descending to 6;000 feet. Both aircraft are being worked by the same controller at this point. They turned Aircraft X to the west and turned Aircraft Y to the east; both at this point descending to 4;000 feet. They decided to change Aircraft X's runway to Runway 36L at the last minute and flashed the data block to my position. Aircraft X was then switched to my frequency without resolving the conflict with Aircraft Y. Once Aircraft X checked in on my frequency; I immediately issued a turn to 200 to avoid Aircraft Y. Once separation was re-established; Aircraft X was vectored back to Runway 36L for the ILS approach.The only thing that I think I could have done to help this situation was ensure that the adjacent sector was turning either Aircraft Y or Aircraft X to avoid each other before I took the hand-off. The conflict should have been resolved before the frequency change occurred.
D10 Developmental Approach Controller reported receiving a handoff of an aircraft that was on a conflicting path with the adjacent sector's traffic.
