I can help assess whether the vector directions shown in your uploaded images are correct by interpreting the contents of each image. Here's how I understand the tasks and questions based on your images:

1. **Image 1 (Parallelogram and Vector Problem):**
   - You are given a parallelogram \( ABCD \) with vector representations:
     - \( \vec{AB} = \vec{u} \)
     - \( \vec{AD} = \vec{v} \)
     - Points \( E \) and \( F \) are midpoints of \( DC \) and \( BC \), respectively.
   - The task is to find the vectors associated with certain geometric relationships (e.g., vectors \( \vec{DE} \), \( \vec{EF} \), etc.).

2. **Image 2 (Vector Operations):**
   - There are several vector operations such as:
     - \( \vec{u} + \vec{v} = \left( \begin{matrix} 4 \\ 1 \end{matrix} \right) + \left( \begin{matrix} 1 \\ -3 \end{matrix} \right) = \left( \begin{matrix} 5 \\ -2 \end{matrix} \right) \)
     - Similar operations are shown with different vectors.

3. **Image 3 (More Vector Geometry):**
   - Further operations involving vectors such as \( \vec{u} - \vec{v} \) and graphical representations of these.

### Answer:
For each of the graphical problems, it is important that:
- The addition or subtraction of vectors follows the correct head-to-tail method.
- The direction of vector subtraction takes into account reversing the direction of the vector being subtracted.
- Vectors should be placed correctly to represent their magnitude and direction.

Would you like me to provide a more detailed explanation of how each vector operation or subtraction is performed geometrically? I can guide you through one of the specific examples from your images.

Here are five related questions:
1. What is the geometric significance of the midpoint of a parallelogram in vector operations?
2. How would you calculate the vector representation of the midpoint between two vectors?
3. Why is vector subtraction treated as the addition of the negative of a vector?
4. Can vector addition result in a vector smaller than both initial vectors? If so, under what conditions?
5. How can you visualize the cross-product of two vectors in a 3D space?

### Tip:
When adding or subtracting vectors geometrically, always follow the head-to-tail method and remember that subtraction is equivalent to adding the opposite vector.
