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

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.
