Answer:
Segment DE is half the length of segment AC.	-- Substitution property of equality
Step-by-step explanation:
Here is given a proof for proving line joining mid segment is parallel and half the length of third side.
Stepwise proof is given in two columns
We find that for every line there is a justification as
STatement                                        Justification
D and E coordinates found out       MId point formula
DE and BC are measured                Distance formula
DE=1/2 BC                                          Substitution property of equality
This justification was missing in the given proof and with this included proof would be complete
 
        
                    
             
        
        
        
Yes that is correct because 4-3 plus 5 is 6 and -6 +8+4 is 6 soo dont stress your self out..Lol
