Question 1166196
<font face="Times New Roman" size="+2">


Your givens are erroneous.  Lines cannot be congruent since they don't have a finite length.  Repost stating the problem correctly and perhaps someone will help with it.  However, even if you call the "lines" by the proper term, I can still construct the five line segments described such that your desired conclusion is false.
