British flag theorem that and by a similar argument the squared lengths of the distances from "P" to the other three corners can be calculated as Therefore: This theorem takes its name from the fact that, when the line segments from "P" to the corners of the rectangle are drawn, together with the perpendicular lines used in the proof, the completed figure somewhat resembles a Union Flag. British flag theorem In Euclidean geometry, the British flag theorem says that if a point "P" is chosen inside rectangle "ABCD" then the sum of the squared Euclidean distances from "P" to two opposite corners of
Facing the Flag Facing the Flag Facing the Flag or For the Flag () is an 1896 patriotic novel by Jules Verne. The book is part of the Voyages Extraordinaires ("Extraordinary Voyages") series. Like "The Begum's Millions", which Verne published in 1879, it has the theme of France and the entire world threatened by a super-weapon (what would now be called a weapon of mass destruction) with the threat finally overcome through the force of French patriotism.
