To use the SSS (Side-Side-Side) Congruence Theorem to establish that \( \triangle ABC \cong \triangle EDC \), you need to confirm that all three corresponding sides of the triangles are congruent.

Given that point \( C \) is the midpoint of both segments \( \overline{BD} \) and \( \overline{AE} \):

1. \( \overline{AC} \) and \( \overline{EC} \) would need to be shown to be congruent.
2. \( \overline{BC} \) and \( \overline{DC} \) would also need to be shown to be congruent.
3. \( \overline{AB} \) and \( \overline{ED} \) should also be shown to be congruent.

Since \( C \) is the midpoint of \( \overline{BD} \) and \( \overline{AE} \), we can conclude:
- \( \overline{BC} \cong \overline{DC} \) (because each segment is half of \( \overline{BD} \))
- \( \overline{AC} \cong \overline{EC} \) (because each segment is half of \( \overline{AE} \))

However, you still need to confirm the congruence of \( \overline{AB} \) and \( \overline{ED} \) in order to apply the SSS theorem.

Among the response options provided, the statement that would provide the necessary additional information is:

**"AB ≅ ED"**

This would indicate that the third pair of sides are congruent and would complete the requirements for SSS congruence, confirming that \( \triangle ABC \cong \triangle EDC \).
