Let A, B, C be sets. Prove that if A is a subset of B and B is a subset of C, then A is a subset of C.?

all the elements found in set A are found in set B if all the elements found in set B are found in set C therefore all the elements in set A which is a subset of set B are found in set C scince set B is a subset of of C

B is a subset of C (B is included in C)


A is a subset of B (A is included in B)


If B is included in C, and A in B, then A is included in C
Reply:Using Venn diagram draw three loops loop represents set A inside loop represents set B which is in side loop represents set C ,then A inside C ,then A is subset of C.
