I think more correctly the vector length of 1/8 inch moved, it does not say which direction and there are 360 degrees of movement that can be considered. The question indicates point A is moved 1/8 inch, (from its original point, not line ABC) as quoted
"If I move point A 1/8" to the left. How much do I have to move point B to maintain a straight line to point C?"
There is not enough information to satisfy the question. That is why it is (as in the thread title) a wacko question. You cannot solve it with exactitude.
