If you can figure out a 45 and a 90 degree angle from point A.You create a point B and C along those lines at anthere called triangles then measure between those two point. For simplicity sake will say its 45 feet. Now you know 1 degree equals 1 foot think you can firgure out the rest yourself at this point. To make it even quicker you could pre mark a rope if you start with a diagram which they do by the way. Obviosly i dont have to assume your level of geometry your proving it.

So again, youre saying it would be simple to create ANY angle required with nothing more than a few lengths of rope ? Perhaps 45, 90, 180 degrees shouldn't be a problem but a design with multiple angles that are NOT derivates of 45 or 90 degrees I would tend to think would NOT be trivial to create ... especially in the dark and on scales of 100's of meters.
Perhaps I'm wrong and it really is simple ... so how would YOU go about creating an exact required angle of say 58 degrees in a wheat field?

Very nice i like that goes back to what i said about using a compass as well the degrees are already marked for you used that in the military when finding locations on a map.

Indeed, I wonder if these same people think aliens made large buildings, sports grounds and roads too.
I once had to set out a 50m x 30m site for a bowling green we were contracted to make, I had a variance of less than 5mm over the whole job.
I did it all with a few string lines, a few pegs, a long tape measure, a plan and a scale rule.
1) Get two pieces of rope.
2) Hold them together at one end.
3) Move the other ends of the rope apart.
4) measure angle with a protractor.
Done.

as I said in the other thread -
throw the rope.

Look at how difficult you all are finding in drawing some as simple as 2 straight lines with a given angle between them ... so imagine the difficulties faced when trying to draw some of the really complicated designs with curves and multiple angles ... just can't be done by people on the ground !
And besides, GPS has only been commercially available since the late 1980s. So how do you explain the ones before that? The really non-complicated ones?
