ughh i need help i dnt like proofs we'll here it the instructions write a two column proof the segment addition postulate is useful for this proof also. remember that the transitive && substitution properties are common in proofs this one requires substitution..
given is rs=xy && st=wx
prove: rt=wy

geometry 
Reiny,
mmmh, I don't think you can prove that.
if rs = xy and st = wx
then
rs/(st) = xy/(wx)
r/t = y/w which contradicts rt = wy
