Is |a − b| < |a − c| ?
Interpretation - is b farther away from a than what c is from a. In other words, is the distance between b and a greater than the distance between c and a

(1) a > 0
Interpretation - a is to the right of centre (0,0)
- still gives us no possible idea about location of b and c
- b can be farther away from a than c, or the opposite also can be possible.

(2) |b| < |c|
interpretation - c is farther away from the centre (0,0) than b
- gives us no possible idea about the location of a
- a can be closer to c than b, or the opposite is also possible

combine (1) and (2)
- a is to the right of centre (0,0) and c is farther away from centre than b is

three possible scenarios:

Case 1
-----[0]------------[a]---------------[b]-----------------[c]

Case 2
---------[0]-----------------------[b]----------------[c]-------------------[a]-------------------------

Case 3
--------[0]---------------[b]-----------[a]-----------------[c]---------------------------------------------


As you can see, many cases are possible,


Case 4
--------------[c]-----------------------[0]-------------------[a]------------------[b]-------------------------

Case 5
---------------[c]-------------[0]-----------------[b]---------------------[a]-------------------------

Case 6
---------------[c]-----------[b]------------[0]----------[a]-------------------------

Therefore both statements together are also not sufficient
