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
Flag of the Soviet Union such a flag was never mass-produced.
