Answer:

1.bd=~ed given

2.CD=~fd given

3.<bdc=<edf

4.triangle BCD=~triangle def by s.s.a.axiom

5.BC=~ef the corresponding side of congruent triangle are equal

Explanation:

in triangle qrs &rst

  1. rs=~rs common side
  2. qr=~st midpoint bisect that side
  3. <qsr=<rst midpoint bisect that angle

4.traingle qrs =~rst by s.s.a.axiom

5.<rqs=<rts since the corresponding angle of congruent triangle are equal
