Question

If ABCD is a square as shown in the figure then which of the following are adjacent sides ?

  1. stack A B with bar on top comma stack A C with bar on top    
  2. stack A B with bar on top comma stack A D with bar on top    
  3. stack B C with bar on top comma stack B D with bar on top    
  4. stack C D with bar on top comma stack C A with bar on top    

hintHint:

look for the vertices which are having an edge between them

The correct answer is: stack A B with bar on top comma stack A D with bar on top


    AB,AD are adjacent vertices
    if two vertices are connected by an edge then they are adjacent vertices
    from diagram we can see that there is a edge between (A,B) and (A,D) thats why they are adjacent vertices

    if two vertices in a graph/diagram  are connected by an edge then they are adjacent vertices
