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
Familiar stranger and evenly distributed. This indicates that person's familiar stranger network can quickly stretch an entire metropolitan area. Wi-Fi usage data for university campuses have provided additional datasets for analyzing familiar strangers. These datasets have yielded similar results as the bus usage data, but the researchers divided relationships based on regularity of interaction and closeness of relationship. Familiar stranger relationships develop in a predictable manner. They depend on regularity, on-going contact, and public spaces. Online social networks are ubiquitous today. But in these digital contexts, it is unclear what defines a familiar stranger relationship. An initial definition put forward has been
