[This is a draft definition awaiting approval by the Challenge Committee.]
A triangle consists of an apex and either a (mini) wave-base or a tandem-base. Triangles are found as
parts of a galaxy, hourglass, twin diamonds, and various other formations.
Teaching Hint: Every dancer has one shoulder toward the inside of the triangle. After Triangle Circulate,
that same shoulder is still toward the center.
Various formations, including Twin Diamonds and Point-to-Point Diamonds, contain Triangles.
Inside Triangle: The Center 6 form the Triangles.
Outside Triangle: The Outside 6 form the Triangles.
The footprints of twin diamonds, with the outside 4 in tandem, contain additional Triangles. Each of
these triangles has one point as the apex and two of the center 4 as the base.
Inpoint Triangle: Each point facing in is an apex.
Outpoint Triangle: Each point facing out is an apex.
Various formations, especially a Galaxy, contain triangles that may be identified by the formation of their
"base". A wave-based triangle has the dancers in the base usually in a mini-wave (also possible: a couple).
A tandem-based triangle has the dancers in the base usually in a tandem (also possible: facing or back-to-back dancers).
Examples of various Triangle Circulates:
