Graphical illustration of the unifying role of s-LGT from A to P: decreasing the value of the R2 for (cc(A, P),cc(A, G)) corresponds to increasing the angle A and X and increasing the value of the R2 for (cc(G, A), cc(G, P)) corresponds to decreasing the angle G resulting in shifting the triangle towards being closer to equilateral. The result of s-LGT from A to G is symmetrical.
