Triangles based on Pythagorean triples are Heronian, meaning they have integer area as well as integer sides. The possible use of the 3 : 4 : 5 triangle in Ancient Egypt, with the supposed use of a knotted rope to lay out such a triangle, and the question whether Pythagoras' theorem was known at that time, have been much debated. [3]
Animation demonstrating the smallest Pythagorean triple, 3 2 + 4 2 = 5 2. A Pythagorean triple consists of three positive integers a, b, and c, such that a 2 + b 2 = c 2. Such a triple is commonly written (a, b, c), a well-known example is (3, 4, 5). If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k.
Rope stretchers used 3-4-5 triangles and the plummet, [2] which are still in use by modern surveyors. The commissioning of a new sacred building was a solemn occasion in which pharaohs and other high-ranking officials personally stretched ropes to define the foundation.
By the finiteness of the number of smaller and smaller potential hypotenuses, eventually (3, 4, 5) is reached. This proves that (d, e, f) does in fact occur in the tree, since it can be reached from (3, 4, 5) by reversing the steps; and it occurs uniquely because there was only one path from (d, e, f) to (3, 4, 5).
[2] [1] The 3-4-5 triangle was used because it is the smallest right-angled triangle with whole-numbered side lengths. However, no Egyptian text before 300 BC actually mentions the use of the theorem to find the length of a triangle's sides.
My go-to method for years has been (for two of us): five large eggs, one large yolk, salt and pepper, and a splash of cream. I cook the whisked eggs in butter, over the lowest heat possible on the ...
