Definition of Degree
The degree of a vertex in a graph refers to the number of edges that are incident with that particular vertex. In other words, it represents the number of connections or links that a vertex has with other vertices in the graph.
Explanation of the Answer
The correct answer is option 'A', which states that the degree of any vertex in a graph is the number of edges incident with that vertex. This means that the degree of a vertex is determined by counting the number of edges that are directly connected to that vertex.
Understanding the Degree of a Vertex
To understand this concept better, let's consider a simple example. Suppose we have a graph consisting of four vertices: A, B, C, and D. The edges in the graph are represented by the lines connecting the vertices.
If we focus on vertex A, we can see that it is connected to three edges: one edge connects A to B, another edge connects A to C, and the third edge connects A to D. Therefore, the degree of vertex A is 3.
Similarly, if we analyze vertex B, we can see that it is connected to two edges: one edge connects B to A and the other edge connects B to C. Thus, the degree of vertex B is 2.
We can follow the same procedure to determine the degree of vertices C and D. Vertex C is connected to three edges (C-A, C-B, and C-D), and vertex D is connected to two edges (D-A and D-C). Hence, the degrees of vertices C and D are 3 and 2, respectively.
Conclusion
In summary, the degree of any vertex in a graph is the number of edges incident with that vertex. It represents the number of connections or links that a vertex has with other vertices in the graph. By counting the number of edges directly connected to a vertex, we can determine its degree.
