From Wikipedia, the free encyclopedia. Taxicab geometry versus Euclidean distance: In taxicab geometry, the red, yellow, and blue paths all have the shortest length of 12. In Euclidean geometry, the green line has length. Displaystyle 6{ sqrt {2} approx 8.49}. And is the unique shortest path. Considered by Hermann Minkowski. In 19th-century Germany, is a form of geometry. In which the usual distance function of metric. Is replaced by a new metric in which the distance. Of their Cartesian coordinates.
