Triangulum Australe (The Southern Triangle)
Triangulum Australe (pronounced traɪˈæŋɡjʊləm ɔːˈstræliː, -ˈstreɪ-) is the Latin name of a constellation situated south of the celestial equator. As such, it is more easily visible from the southern hemisphere.
In English language this constellation is also known as "The Southern triangle" while in astronomical texts and literature this constellation is often abbreviated as "TrA" (according to the standard of the International Astronomical Union - IAU) or as "TrAu" (according to a naming convention used by NASA).
The Latin genitive of the constellation name is "Trianguli Australis" (pronounced traɪˈæŋɡjʊlaɪ ɔːˈstrælɪs) and it is used to identify some of the brightest stars in this constellation based on the Bayer or Flamsteed star naming convention. For instance: α Trianguli Australis (the brightest star of Triangulum Australe based on the Bayer catalog); or 23 Trianguli Australis (the 23th star in the constellation of Triangulum Australe based on the Flamsteed catalog).
