Solutiion of the original problem

Corrections:

In the figure |FG| has to be replaced by |AG|

and Solutiion by Solution!

Note that the general solution proves the theorem of Pythagoras, with an interesting link to the generation of Pythagorean triples, and in fact the problem is closely modelled on the recent proof of that theorem by Jackson and Johnson.
