Hi Robin. I am having a lot of trouble duplicating this diagram of yours. According to my research the SW corner of G2 does not get ticked when using, as the radius, a line from the west side of The Giza Rectangle to the centre of G2 ( which I have as [sq rt of 5 divided by 4] x 1000 or 559.017 cubits. What distance did you use for the radius to make it fit remembering that according to most researchers the east co-ordinate is E 353.5534. So as I see it the diagonal from NW corner of G3 to SW corner of G2 should be 559.017 cubits but this would make our triangle as sq rt of 2 (short side) and sq rt of 5 (as the diagonal). This would make the north-south distance sq rt of 3 or 433.013 but this is not possible as I see it for it would make the distance from south side of G2 to south side of G3 as 433.013 + 201.46 = 634.473 far too large to fit the known measurements. So I am curious as to what measurement you used.
Best regards
