Descriptive — the legs-form-the-triangle choke
Leg triangle is a descriptive name for the standard triangle — distinguishing the legs-applied strangle from arm-applied head-and-arm chokes.
Etymology. “Leg triangle” specifies that the legs, not an arm, form the triangle around the neck and shoulder; “triangle” names the strangle. The label clarifies which limbs close the choke, useful where “triangle” alone is ambiguous.
Mechanics. The legs trap the head and one arm, and the opponent’s trapped arm fills one side of the neck while the legs press the other; because the arm is in, the strangle must compensate by angling and driving the knee across so both carotids compress despite the arm occupying space the legs would otherwise close.
Cross-reference. “Triangle choke” and “Standard triangle” are sibling aliases. Full mechanical coverage on Standard Triangle.
