Triangle from mount positionThe triangle is one of the most iconic submissions in Brazilian Jiu-jitsu. It occurs when your opponent's head and one arm are trapped between your triangled legs, and pressure is applied to reduce circulation to and from the brain. Triangles can be executed from many different positions, but perhaps the most common is the triangle executed on an opponent while transitioning from closed or open guard with your opponent facing you. A reverse triangle is executed when the opponent is facing away from you.
