Hyperbolic Triangle Centers
The study of triangle centers traditionally is concerned with Euclidean geometry, but triangle centers can also be studied in hyperbolic geometry. Using gyrotrigonometry, expressions for trigonometric barycentric coordinates can be calculated that have the same form for both euclidean and hyperbolic geometry. In order for the expressions to coincide, the expressions must not encapsulate the specification of the anglesum being 180 degrees.

Famous quotes containing the word centers:
“But look what we have built ... low-income projects that become worse centers of delinquency, vandalism and general social hopelessness than the slums they were supposed to replace.... Cultural centers that are unable to support a good bookstore. Civic centers that are avoided by everyone but bums.... Promenades that go from no place to nowhere and have no promenaders. Expressways that eviscerate great cities. This is not the rebuilding of cities. This is the sacking of cities.”
—Jane Jacobs (b. 1916)
