we know that
If C is between A and B
then
[tex]AB=AC+CB[/tex]
Examples
N [tex]1[/tex]
Let
[tex]AB=10\ units \\AC=5\ units[/tex]
Find the value of CB
substitute in the equation above
[tex]AB=AC+CB[/tex]
[tex]10=5+CB[/tex]
[tex]CB=5\ units[/tex]
in this case
[tex]AC=CB[/tex]
N [tex]2[/tex]
Let
[tex]AB=10\ units \\AC=8\ units[/tex]
Find the value of CB
substitute in the equation above
[tex]AB=AC+CB[/tex]
[tex]10=8+CB[/tex]
[tex]CB=2\ units[/tex]
in this case
[tex]AC\neq CB[/tex]
therefore
the answer is
sometimes
