A triangularly shaped wing of an aircraft.

delta wing

A wing plan form that is shaped like a triangle, or a delta (A). In this type of wing, there is an extreme amount of sweep back on the leading edges, and a trailing edge that is practically perpendicular to the longitudinal axis of the aircraft. A delta wing aircraft may be part of a tailplane, or it may be tail-less. This plan form is used on supersonic aircraft. See delta (iii).
