I simply used only the grid system. No trig. no compass. no protractor. " I started with the rules for a compass and straight-edge construction of a pentagon" - you. I started only with the grid and my pip. It took 14 years of persistence but the construction only has 7 lines and you have a...

Yes my goal was to construct a pentagon without trig or the use of a compass. What was the accuracy of you angles with your construction? If you say you started with the rules for a compass and straight-edge construction of a pentagon then you "tried" it without trig but not without a compass...

I have found a way to construct a pentagon using only the grid system. The internal angles are all within 99% accuracy and all the angles to the 3rd decimal add up exactly to 540 degrees. This is without the use of a compass and bearing in mind that the internal lines intersect at the ration of...
