Since you are given two sides congruent to two sides, if you have a third pair of congruent sides, you'll be able to use SSS. 
Well, here comes the reflexive property to tell us that BD = BD. Then using the definition of congruent segments, you can say segment BD is congruent to segment BD. 
Now you have SSS and you prove the triangles congruent.
As you can see, the reflexive property came in handy.
