Delta wing

wing shaped in the form of a triangle

A delta wing is a wing used on fixed-wing aircraft, mainly supersonic fighter aircraft. Delta wings are triangles. Some were "tailless" (which means they had no elevators) and others were "tailed." Many of the Dassault Aviation Mirages had delta wings (like the Mirage III, Mirage V, Mirage 50, and Mirage 2000).
