The diagram shows two segments that are marked congruent to each other with a small line segment across them. These segments are $JI$ and $HG$.

So, the answer is:

$JI$ is congruent to $HG$

2. How can you prove two segments are congruent using geometric postulates?
3. What other pairs of congruent segments can exist in a different geometric figure?
4. How does congruence relate to similarity in geometric figures?
5. Can two segments be congruent if they are not parallel?

Tip: In geometric diagrams, look for specific marks like small line segments or angles that indicate congruence or equality. These visual cues help identify relationships between different parts of the figure.
