Geometric Proofs....

Write a justification for each step

Given: AB = EF, B is the midpoint of Line AC and E is the midpoint of Line DF.

1. B is the midpoint of Line AC and E is the midpoint of Line DF.

2. Line AB is congruent to Line BC and Line DE is congruent to Line DF

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. Line AC is congruent to Line DF

What are the justfications?
