HELP!! Geometry Proofs!

Look at the picture in the question if one wants to find further details;

Answers are in the format;

Statement                           Reasons

Problem 1

1) AB = CB                            given

2) AD = CD                           definition of midpoint

3) DB = DB                           reflexive property

4) ABC = CBD                     side-side-side congruency

Problem 2

1)AB = CB                               given

2) m<A = m<C                        given

3) CD = CD                            reflexive property

4) ABD = CBD                        side-angle-side congruency

5) AD = CD                             corresponding parts of congruent triangles are                             .                                               congruent

Problem 3

1) CG = CD                                     Given

2) CGD-isosceles triangle            Definition os isosceles triangle

3) m<CDG = m<CGD                    Base angles theorem

4) DF = GF                                     Given

5) CDE = CFG                               side-angle-side

6) CE = CF                                     corresponding parts of congruent traingles .                                                       are congruent

what are the options? ?
