Let's analyze the image and classify the pairs of lines as either **Parallel**, **Perpendicular**, or **Cannot Be Determined** based on their relationships in the diagram.

### Analysis:
1. **Lines AB and CD:**
   - These two lines are horizontal and both appear to be straight and equidistant from each other across their lengths. Hence, they are **parallel**.

2. **Lines CD and GH:**
   - Line CD is horizontal, while line GH is vertical. As horizontal and vertical lines meet at a right angle (90°), they are **perpendicular**.

3. **Lines AB and GH:**
   - Line AB is horizontal, while line GH is vertical. Since horizontal and vertical lines form a right angle (90°), these lines are also **perpendicular**.

4. **Lines IJ and CD:**
   - Both IJ and CD are horizontal and appear to be equidistant from each other, making them **parallel**.

### Classification:
1. AB and CD - **Parallel**
2. CD and GH - **Perpendicular**
3. AB and GH - **Perpendicular**
4. IJ and CD - **Parallel**

### Related Questions:
1. How can you identify parallel lines from a diagram?
2. What are the geometric properties of perpendicular lines?
3. Are there any exceptions where lines that look perpendicular may not be?
4. Can two lines be perpendicular in 3D space but not in 2D space?
5. How do you calculate the angle between two lines if they are neither parallel nor perpendicular?

### Tip:
When determining if lines are parallel, always check for equal spacing and alignment. To verify perpendicularity, ensure the lines form a 90° angle using visual cues or tools like a protractor.

Use this image to classify each pair of lines. Select Parallel, Perpendicular, or Cannot Be Determined to classify each pair of lines: AB and CD, CD and GH, AB and GH, IJ and CD.
