Menger's Theorem is a fundamental result in graph theory, particularly dealing with the connectivity of graphs. It relates the minimum number of vertices (or edges) that need to be removed to disconnect a graph to the maximum number of vertex (or edge) disjoint paths between two vertices.

Here’s a breakdown of Menger's Theorem in the context of the graph you provided:

### Menger's Theorem (Vertex Version)
For any two non-adjacent vertices \( u \) and \( v \) in a graph, the minimum number of vertices that must be removed to separate \( u \) and \( v \) (i.e., to make \( u \) and \( v \) belong to different connected components) is equal to the maximum number of vertex-disjoint paths between \( u \) and \( v \).

### Menger's Theorem (Edge Version)
For any two vertices \( u \) and \( v \) in a graph, the minimum number of edges that must be removed to separate \( u \) and \( v \) is equal to the maximum number of edge-disjoint paths between \( u \) and \( v \).

### Applying Menger's Theorem to the Provided Graph

1. **Identify two vertices**: Choose any two vertices on the graph to apply Menger's Theorem. For example, let's choose vertices \( A \) and \( B \).

2. **Find Vertex Disjoint Paths**: Determine the maximum number of vertex-disjoint paths between these two vertices.

3. **Find Edge Disjoint Paths**: Determine the maximum number of edge-disjoint paths between these two vertices.

4. **Minimum Cut**: Check the minimum number of vertices or edges that need to be removed to disconnect the chosen vertices.

### Example:

If we consider vertices \( A \) and \( B \):

1. **Vertex Disjoint Paths**: Count the number of paths between \( A \) and \( B \) that do not share any vertices other than \( A \) and \( B \) themselves.
   
2. **Edge Disjoint Paths**: Count the number of paths between \( A \) and \( B \) that do not share any edges.

3. **Minimum Cut**: The theorem then tells us that the minimum number of vertices (or edges) that needs to be removed to disconnect \( A \) from \( B \) is equal to the number of vertex-disjoint (or edge-disjoint) paths.

Given the graph image, we can analyze it more specifically if you choose particular vertices.

### Tip:
When applying Menger's Theorem, always verify whether you are dealing with vertex-disjoint paths or edge-disjoint paths, as the concepts are closely related but involve different calculations.
