To determine whether the given graph has an Euler path, we need to recall a few key points about Euler paths:

Euler Path Definition:

An Euler path is a path in a graph that visits every edge exactly once. A graph will have an Euler path if and only if:

1. Exactly two vertices have an odd degree (number of edges), and the rest have even degrees.
2. The graph must be connected (i.e., every vertex must be reachable from any other vertex).

Now let's analyze the graph from the image you uploaded:

Step-by-step procedure:

1. Count the degree of each vertex:

   • A vertex's degree is the number of edges connected to it.
   • Let's label each vertex and then determine the degree of each one by counting the number of edges touching each vertex.

2. Check the conditions for an Euler path:

   • If exactly two vertices have an odd degree, then the graph will have an Euler path.

Let me analyze and count the degrees of the vertices now.I have opened the image to examine the graph. Now, I will guide you step-by-step through determining whether it has an Euler path.

1. Label each vertex and determine how many edges are connected to each vertex (its degree).
2. Check for vertices with odd degrees. If exactly two vertices have odd degrees, the graph has an Euler path.

Analysis of the vertices:

• There are 10 vertices (forming the letters C, U, B, S).

• Let's count the edges for each vertex based on their connections.

• Vertex 1 (top-left of 'C'): Degree = 2 edges.

• Vertex 2 (bottom-left of 'C'): Degree = 2 edges.

• Vertex 3 (top-right of 'C'): Degree = 3 edges (1 edge connected to vertex in 'C', 1 to 'U').

• Vertex 4 (middle-right of 'C'): Degree = 3 edges (1 edge within 'C', 2 to 'U').

• Vertex 5 (top-left of 'U'): Degree = 2 edges.

• Vertex 6 (bottom-left of 'U'): Degree = 2 edges.

• Vertex 7 (top-right of 'U'): Degree = 2 edges.

• Vertex 8 (bottom-right of 'U'): Degree = 2 edges.

• Vertex 9 (middle-left of 'S'): Degree = 3 edges (1 from 'B', 2 to 'S').

• Vertex 10 (bottom-right of 'S'): Degree = 2 edges.

Conclusion:

There are two vertices with odd degrees (vertices 3 and 9), meaning the graph does satisfy the condition for having an Euler path.

Thus, this graph has an Euler path.
