If I followed all of Patrick's advice, I would have twin roll bars, a solid flat tappet cam and live somewhere cold and lonely!

No, you would be healthier, wealthier, and wiser....  And you know that.  |

Actually it.would not.be perpendicular to either line. It would form.an isosceles.triangle.

What if points A B and C were all along the same line and the line goes left to right. Then you move point A to the left (along this line). Think about it.

Ok, but what if ABC were in space where there is no up/down or left/right?

Sorry, that was a stupid question on my part in retrospect.
I can only really relate in construction terms, which I think is what Car Nut was leading to.
"If I have my surveyor's transit over point A, and I'm looking at Joe, who is holding the target at point B, and in between I have Patrick holding target C, which is directly in line with my sight of Joe, then I move my instrument to get back to my direct line of sight with Joe. Now, how much do I tell Joe to move over to get Patrick back in my direct line of sight?" Hey, I'm tryin'!

So, back to my previous example, let's say I move my transit 2 feet to my right and re-sight it in to Joe (B). Now I have direct line of sight to Joe, but I can't see Patrick (C) anymore and he can't move. Patrick wants to be back in the picture between Joe and I. Don't I just tell Joe to move 2 feet to his right as well? Is it that simple?

No, but it might matter if Patrick is taller.

Not only taller, but better looking and with a wonderful sense of humor as well. |

Then you could knock Tom Cruise out of the running to play Carroll Shelby in the upcoming movie!

BTW, "Joe" is actually Mike, but he was working a side-job for cash and Patrick was getting pissy because he wasn't allowed to move to get back in the direct-line shot between Mike and I.

If you have your transit looking at target B. Target C would be at some point beyond B. When you.move A you change so that line.A B no.longer points directly at.point C.

But what if a or b moves along the line towards or away from you.

From me? Or from a stated point?? That wouldn't matter, would it? Because AB are a constant straight line. They could be in motion and will always retain a straight line.
And please don't tell me I have to factor in the curvature of the earth! 
I'm just a dumb-ass carpenter, but I'll keep playing

Then the intercept line would get longer or shorter depending on which one moves and which way it goes.

Everyone is sober, so they all walk a straight line.

It's a high school trig problem. Originally ABC were on a line. A' is 1/8' (we assume at a right angle to the original ABC line. If A' is 1/8" along the original ABC line then B does not move. No matter what we need to know the angle of A' vs the original ABC line.
Then the new line is A'C. The problem to be solved is the location of B' (where the new line is A'B'C.
It ought the be a solution for a right angle triangle.
But we need to know the precise location of A' first.
If this is a theoretical problem where all of them are zero dimensioned points there will be an answer. if this is a practical problem then just overdrill the f'n hole at B' and get over it. A bolt and washer washer will cover it. 
If you need an engineer stamped drawing find a PE.
