Front triangle
Also known as Reverse Triangle — the canonical term used on this site.
Training background: colloquial — anterior approach
Informal — the front-facing reverse triangle
Front triangle is a colloquial name within the reverse triangle entry — used loosely for the front-facing orientation the reverse triangle can be entered from.
Etymology. “Front triangle” is informal and somewhat imprecise, naming the lock by a front-facing angle; it is grouped here with the reverse triangle, whose orientation it describes from the opposite reference. Precise vocabulary names the specific entry.
Mechanics. The strangle is set by the angle of the legs to the neck: a force angle that lines the legs across both carotids finishes the choke, while a square angle catches only one side. Whatever the entry is called, the lock works by establishing the angle that loads both sides of the neck rather than by squeezing harder.
Cross-reference. “Reverse leg triangle” is a sibling alias. Full mechanical coverage on Reverse Triangle.
