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 United Arab Emirates white bar at the hoist, i.e. closest to the flag staff. Before 1952, the flag of Fujairah was plain red. Fujairah did not sign the general treaty in 1820 with the British protectorate and therefore is still using its red plain flag. In 1952, the emirate's name was added to the flag, and a red flag with a white Arabic calligraphy of the emirate name was adopted as an ensign to distinguish it from the surrounding emirates. The flags of Ras Al Khaimah and Sharjah are identical as they are both ruled by two branches of the same house. They
