There are two cases:
Case 1:C is a subset of B.
\(C \subset B\)
The venn diagram of A should be completely within the venn diagram of C since A is a subset of C.
The venn diagram of C should be completely within the venn diagram of B since C is a subset of B.
Case 2:B is a subset of C.
\(B \subset C\)
The venn diagram of A should be completely within the venn diagram of B since A is a subset of B.
The venn diagram of B should be completely within the venn diagram of C since B is a subset of C.
Now, the overall venn diagram for \(A \subset B\) and \(B \subset C\)is:
Thus, \(A \subset B\) and \(B \subset C\) is illustrated using Venn diagram.
