Law of the Triangle
From The Rosicrucian Manual 1918 (sixth edition 1934)
“Trigonometry (from Greek trigōnon “triangle” + metron “measure”) is a branch of mathematics that deals with triangles, particularly those plane triangles in which one angle has 90 degrees (right triangles). Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships.”— Wikipedia
Triangulation is a technique used also to measure the height of buildings, the distance of stars if they aren’t too far away, the motion of planets, to locate people by their cell phone, to make maps, … all sorts of things. The Arabs and Phoenicians became excellent navigators of spaces without landmarks through the use of triangles. The Egyptians kept track of the height of Sirius in the sky as well as many other things using triangles. The sides of pyramids worldwide are made of 4 triangles.
