Explanation:

1. The first drawing is a line segment with endpoints C and D, which matches the notation $CD$.
2. The second drawing is a line passing through C and D (arrows on both ends), which matches the notation $\overleftrightarrow{CD}$.
3. The third drawing is a ray starting at D and extending through C (arrow at C), which matches the notation $\overrightarrow{DC}$.
4. The fourth drawing is a ray starting at C and extending through D (arrow at D), which matches the notation $\overrightarrow{CD}$.

Answer:

• First drawing (segment CD) ↔ $CD$
• Second drawing (line CD) ↔ $\overleftrightarrow{CD}$
• Third drawing (ray DC) ↔ $\overrightarrow{DC}$
• Fourth drawing (ray CD) ↔ $\overrightarrow{CD}$
