If C is any point on the line ←→AB , it is also a part of the line ←→BC .
True
If A and B are any two points on a line, we represent it as ←→AB.
Now, if C is another point on the same line, we can use points B and C to describe this line as ←→BC.
Since we are representing the same line, hence the above statement in the question is True.
