In trigonometry and geometry, triangulation is the process of determining the location of a point by measuring angles to it from known points at either end of a fixed baseline. The point can then be fixed as the third point of a triangle with one known side and two known angles. The use of triangles to estimate distances goes back to antiquity. In the 6th century BC the Greek philosopher Thales is recorded as using similar triangles to estimate the height of the pyramids by measuring the length of their shadows and that of his own at the same moment, and comparing the ratios to his height. He has also estimated the distances to ships at sea as seen from the top of a cliff, by measuring the horizontal distance traversed by the line-of-sight for a known fall, and scaling up to the height of the whole cliff.
Triangulations is a series of peyote woven 3-D triangles. They are linked with matching rings or disc beads. The simplicity and clean lines of the various geometric shapes gives this necklace an extremely elegant and sophisticated feel.
The necklace is simple enough for those who have just started beading and yet interesting enough for the experienced beaders to enjoy.
