This is because triangles in a tree are tripods.
When the two new swing leg paths have been found, a new tripod can be constructed.
Each tripod has its own maximum turning angle and three corresponding optimal leg paths.
A tripod is placed on the ground in the position, relative to the body, which corresponds to the start of its stroke.
They should then proceed to walking exercises, using a tripod or walking stick if required for extra support.
The algorithm needs only a few iterations to find the optimal tripods.
The angular strokes associated with the two tripod supports must connect with each other.
Ring bases with their hallmark stepfret or triangle cut-out windows are more common than tripod supports.
