In 1998 RCHME published the U I 433143 for KAH and gave dimensions as 159 x66 feet. Thus 66 feet is 14 x 4.714 feet the part of the 30/60/90 triangle of 2.722 x 4.714 x 5.444 feet 1/root3/2. Then in 2008 EH published Bodmin Moor Vol 1 and on Figire 19 produced 2 plans of the KHA. (Thus in 1998 it was Megalithic using Prof Thom's figures. But no plot published.)
Figure 19 allows for the geometry to be established with the Stones being a 5/12/13 triangle ( see AndyB 07/11) surrounded by a rectangle with the crest of the banks being basically a 1/2/Root5 triangle. Why does it work, because the hypotenuse of the stones triangle is the same length as the N/S side of the banking at 36 x4.714, the figures being 18 x 36 x 40.25 for the Banking triangle which sits symmetrically over the stones rectangle.
Go back to 1998 and work it all out with the 2008 plans.
