If A B and B C,( boxex are a U turned to the right with a line under it) what can you conclude? Why? What if A B and B C? (these squres are a U turned right with no line under it. If A B and B C ( 1st square has the U turned right w/line square 2 has U with no line.

You can put this solution on YOUR website! If A B and B C,( boxex are a U turned to the right with a line under it) what can you conclude? Why?
Ans: If A is a subset of B and B is a subset of C then A is a subset of C.
Why?: If a is an element of A, it is an element of B because A is a subset of B.
But if a is an element of B, then it is an element of C because B is a subset of C.
---------------------
What if A B and B C? (these squares are a U turned right with no line under it.
Ans: If A is a proper subset of B and B is a proper subset of C, then A is
a proper subset of C.
----------------------
If A B and B C ( 1st square has the U turned right w/line square 2 has U with no line.
Ans: If A is a subset of B and B is a proper subset of C, then A is a subset
of C.
