Explanation:

Step1: Identify segment CD

The first figure is a line segment with endpoints C and D, which matches $CD$.

Step2: Identify line CD

The second figure is a line passing through C and D (arrows on both ends), which matches $\overleftrightarrow{CD}$.

Step3: Identify ray DC

The third figure is a ray starting at D and extending through C (arrow at C end), which matches $\overrightarrow{DC}$.

Step4: Identify ray CD

The fourth figure is a ray starting at C and extending through D (arrow at D end), which matches $\overrightarrow{CD}$.

Answer:

1. First drawing (segment CD) ↔ $CD$
2. Second drawing (line CD) ↔ $\overleftrightarrow{CD}$
3. Third drawing (ray DC) ↔ $\overrightarrow{DC}$
4. Fourth drawing (ray CD) ↔ $\overrightarrow{CD}$
