Actualy, I think you've done a remarkably good job of explaining this.

And with your brief discussion of triangles, you've basically explained
how to use this system to measure distances *away* from theruler.

Pircutre a point off the line

A

---------------------|---------------|------------
B               C

Now points B and C will form a triangle with A, and we'll have two angles
and a side, which is enough to fully describe the triangle (using the law
of sin and the law of Cos)  so we can then find the distance AC, or BC, or
the distance from A to BC.
