1. The problem asks to list all line segments that have the same length as segment $CH$. 2. From the graph description, segment $CH$ is marked with three short hash marks indicating its length. 3. Other segments with the same number of hash marks (three) are the ones equal in length to $CH$. 4. According to the description, segment $EI$ also has three hash marks. 5. Therefore, the line segments equal in length to $CH$ are $CH$ and $EI$. 6. The other segments have different numbers of hash marks and thus different lengths. Final answer: The line segments with the same length as $CH$ are $CH$ and $EI$.
