1. **Is the object square-shaped?**
   - **Answer:** No
   - **Reasoning:** The images show that the object has four equal sides and equal angles, which initially suggests a square shape. However, the orientation of the object in the images indicates that it is actually a diamond shape or a square rotated by 45 degrees. The angles at the corners appear to be right angles, but the overall orientation is not aligned with a typical square's horizontal and vertical alignment.

2. **Is the object slightly extruded?**
   - **Answer:** Yes
   - **Reasoning:** From the images, it is evident that the object has some thickness, indicating that it is not merely a flat square but has some extrusion or depth. This can be observed from the shadows and the edges visible in different orientations, showing that the object has a 3D form.

3. **Is there a small hole in the center of the square?**
   - **Answer:** Yes
   - **Reasoning:** In all the images provided, there is a visible small dot or hole located at the center of the object. This consistent feature in all orientations confirms the presence of a small hole at the center.
