The triangle choke applied at an early judo tournament.
A triangle choke, or sankaku-jime (三角絞) in Judo, is a type of figure-four chokehold which strangles the opponent by encircling the opponent's neck and one arm with the legs in a configuration similar to the shape of a triangle. The technique is a type of lateral vascular restraint that constricts the blood flow from the carotid arteries to the brain.
The triangle choke was seen in early Kosen judo competition. Tsunetane Oda, a judo groundwork specialist who died in 1955, had demonstrated the triangle choke on video. The move is often used in grappling and mixed martial arts. The front triangle is particularly favored by adepts of Brazilian Jiu-jitsu. More recently, several side or inverted triangles, typically seen more often in Judo competition, have been used in higher-profile MMA matches.

Tactically speaking, the triangle choke is a very effective counter attack easily employed from the bottom position, generally applied from the guard, or open guard (defensive positions). The need for isolation of one arm could be a rationale for the frequency with which it is attempted in mixed martial arts and combat sports due to the brief vulnerability of one arm while executing hand strikes against an opponent in one of the aforementioned positions.
Defensive Action 
To escape a triangle choke, the defending practitioner must first elevate the head so as the preclude the full force of the submission, subsequently the practitioner must bring his arm away from opposition with his own carotid artery. Once out of immediate danger of loss of consciousness, the practitioner can concentrate reversing or escaping the figure-four lock.
