Write a justification for each step. Given: AB = EF, B is the midpoint of AC,
and E is the midpoint of DF.
1. Bis the midpoint of AC,
and E is the midpoint of DF.
2. AB = BC, and DE = EF.
3. AB = BC, and DE = EF.
4. AB + BC = AC, and DE + EF = DF.
5. 2AB = AC, and 2EF = DF.
6. AB = EF
7. 2AB = 2EF
8. AC = DF
9. AC EDF
