It messed up the first time I tried typing it up so I hope this is better

3.  Parallel llines cut by a transversal make corresponding angles equal

4.  

6.        Parallel lines cut by a transversal make interior angles equal                            

7.  Transitive Property of Congruence 

8.  EB congruent to AB    Sides opposite equal  angles in a triangle are ccngruent 

9. EB = AB

10.  AD   =       AB

       DC            BC    

I'm not toally sure about Step 9, but....I did my best....!!!

4 is not showing up

It should be that

angle ABD  =  angle DBC
