you want to mask the foreground with the polygon and then move the masked element over the BG?
you can attach the mask directly into the loader of the foreground or my way would to combine the mask and the foreground with a MatteControl node ("combine alpha" and check "post multiply image").
the add a transform node and then use a merge to combine the FG and BG element.
now you can move the cutout FG with the transform over the BG
