Reorder the steps of the proof to make sure that steps that are logically dependent on prior steps are in the proper order. Given: DD is the midpoint of \overline{AC},
AC
, \overline{ED} \cong \overline{FD}
ED
≅
FD
and \angle FDA \cong \angle EDC.∠FDA≅∠EDC.

Prove: \triangle ABC△ABC is an isosceles triangle.
