1. **Is the object triangular in shape?**
   - **Answer:** Yes
   - **Reasoning:** From all three images, the object consistently shows a triangular face or base, indicating that it is triangular in shape. Each image displays a different orientation, but the triangular aspect remains evident.

2. **Is the object extruded in one dimension?**
   - **Answer:** Yes
   - **Reasoning:** The images show that the object has a consistent cross-sectional shape (triangular) along one dimension, suggesting it is extruded. The uniformity of the shape across different views supports this observation.
