Trimmer resistor rookie question

[Don]

If a circuit schematic looks like:
(a)
---------o---R4K7---------o
^ |
| |

|

/< R10K >
/ > < R4M7
/ | >
| |
---(b)-------(c)-----------

(b and c are not in the original schematic, my example only for clarity)

And a trimmer has 3 terminals 1
2 3

Does the trimmer terminals 1 2 3 correspond to my example a b c
or do I just wire it up as 1-a, 2-b like as connected as a variable
resistor/rheostat?
I suppose I just thought I knew how a trimmer works.

Appreciate any help;
Thanks; Don

In this instance, its no different to a variable resistor !
