### Given:

\(\overline{GJ}\) bisects \(\overline{FH}\), and \(\overline{FH}\) bisects \(\overline{GJ}\).

### Prove: 

\(\triangle FGK \cong \triangle HJK\)

### Diagram Explanation:

A geometric diagram is shown on the right side which consists of two intersecting lines, labeled \(\overline{FH}\) and \(\overline{GJ}\). The intersection point of these two lines is labeled \(K\).

- The endpoints of one line are marked as \(F\) and \(H\).
- The endpoints of the other line are labeled \(G\) and \(J\).

### Conjecture:

Based on the given information, we need to prove that the triangles \( \triangle FGK \) and \( \triangle HJK \) are congruent to each other.

### Approach:

To prove the congruence of the two triangles:
1. Utilize the fact that \( \overline{GJ} \) and \( \overline{FH} \) are bisected at their intersection point \( K \).
2. Use geometrical properties and congruence theorems such as Side-Angle-Side (SAS) or Angle-Side-Angle (ASA) to show the required congruence.

This problem involves applying the concepts of line segment bisectors and triangle congruence to arrive at the solution.
