1)K is the midpoint of line 1 1) given
JE 1
2)line KE is congruent to 1 2) midpoint is the center of a line segment
line KJ 1
3)L is the midpoint of line 1 3) given
UN 1
4)line NL is congruent to line 1 4) midpoint is the center of a line segment
LU 1
5)line KL and line UE bisect 1 5) given
each other at M 1
6)line EM is congruent to line 1 6) line bisector splits the line segment in half
MU 1
7)line KM is congruent to line 1 7) line bisector splits the line segment in half
ML 1
8)triangle EKM is congruent to1 8) theorem of Side,Side,Side
triangle ULM 1
9)line EK is congruent to line 1 9)corresponding parts of congruent triangles and congruent
UL 1
10)line KJ is congruent to line 1 10)substitution
NL 1
11)line EJ is congruent to line 1 11)substitution
NU 1
This is where i am stuck,how can I prove that either line EN is congruent to line JU or that line EJ is parallel to line NU?

for some reason the picture isn't coming out on this part. it is suppose to be a diagnol EU and a line NU.

Why is this a "calculus and beyond" question? Looks like basic geometry to me.

Also I don't see any indication of what YOU have done. If we don't know what kind of help you need, we can't give you any help.

You need to prove that triangle MNL is congruent to triangle JMK. Look at the angles NLM and JKM.
