Sorry. What's "Trisects", "Diagonal" and "Midpoint" in this situation? Definitions are always different for different questions.

Trisects  divided equally in 3 parts. Diagonal  from one corner to the opposite. Mid point  midway. Fairly basic.

Do you need to use formulas? Because I think a diagram on graph/grid paper would work fine.

Formula? I'm not sure. All vectors laws are straight forward in my opinion.

Maybe its trisecting the parallelogram itself? Not sure. What course is this? Vectors?

Let me show you the solution. This is how they draw it. Page 1: https://dl.dropbox.com/u/63664351/Mathematics%20at%20Alevel/20130105_151348.jpg Page 2: https://dl.dropbox.com/u/63664351/Mathematics%20at%20Alevel/20130105_151457.jpg I don't understand why AM=FM=1

if you can see why those two triangles are similar then the rest is a matter of ratios
