Provide the missing reasons for the proof of part of the triangle midsegment theorem. given: k is the midpoint of line mj. l isthe midpoint of line nj. prove mn =2kl

statement:
1. k is the midpoint of line mj. l is the midpoint of line nj
2. line mk is parallel to line kj and line nl is parallel to line lj
3. mk = kj and nl = lj
4. mj =mk +kj and nj = nl+lj
5. mj = 2kl and nj = 2lj
6. mj/kj = nj/lj = 2
7. angle j is parallel to angle j
8.triangle jmn is congruent to triangle jkl
9. mn/kl = mj/kj
10. mn/kl = 2
11. mn = 2kl

reason:
1.
2
3.
4.
5. substitution property of equality
6. division property of equality
