This page needs a rewriting (if it is needed at all). The first problem is "in geometry" in the very beginning. In geometry the concept is not needed as in geometry of metric spaces all lengths are "true" and other spaces have not lengths at all. The term makes sense and is used in descriptive geometry, including cartography, and in engineering and other arts that use these. However, the definition should be more precise. In particular, what does "true length" mean in context of scaled drawings? The definition given here restricts the term to the distance between certain endpoints whereas other sources define it so that (in a typical application) there is a true length (or true distance) between every pair of points. 213.216.254.92 (talk) 08:26, 20 June 2013 (UTC)
