Triangulum Australe (pronounced /traɪˈæŋɡjʊləm ɒsˈtreɪliː/, Latin: South Triangle) is a small southern constellation whose three brightest stars, of second and third magnitude, form an approximately equilateral triangle. This constellation was introduced by Johann Bayer in 1603.
Since it was introduced in the 17th century, there is no earlier mythology associated with it.
