This is my problem:
On my knife sharpener, there is a Clamp that holds the blade vertically, edge up. At the base of the clamp and perpendicular to the blade, there is a Base Rod with a Pivot Point that slides along the Base Rod to establish an angle relative to the blade. The third side of the triangle is created by the sharpening media sliding on a Guide Rod, anchored at the Pivot Point. T triangle could be described as follows: Side A = height of the Clamp + height of blade above the clamp. Side B = Distance along Base Rod between the Pivot Point and Side A. We can calculate the angle AC knowing that angle AB is a right angle and knowing the length of Side A and Side B. Where I run into problems is proving that the angle of the sharpening media will remain constant along the length of the blade. The diagrams below help illustrate the issue.

In the diagrams, the Clamp is 6" and the distance of the Pivot Point from the clamp is 6". The height of the knife above the clamp is 1". I can see that the sharpening medium stays in the same plane relative to the knife, I just can't remember a way to prove it.
Any help would be most appreciated.
