Interlocked Triangles consist of two adjacent Triangles, whose Centermost dancers are working with the furthest Outside dancers in a Triangle.

Examples of (symmetric) Interlocked Triangles:

dancers work together in one Triangle as the dancers work together in another Triangle.

In general, Interlocked formation means that (viewing the formation along its long axis) one plane of dancers from each of two formations is interspersed with the other formation.

From a Galaxy in which the Centers are non-T-Bone, there are both Interlocked Wave-Based Triangles and Interlocked Tandem-Based Triangles.

From Twin Diamonds there are four sets of Interlocked Triangles: Inside Interlocked Triangles (a.k.a. Interlocked Diamond Inside Triangles):   ,, and ,, Outside Interlocked Triangles (a.k.a. Interlocked Diamond Outside Triangles):   ,, and ,, Inpoint Interlocked Triangles (a.k.a. Interlocked Diamond Inpoint Triangles):   ,, and ,, Outpoint Interlocked Triangles (a.k.a. Interlocked Diamond Outpoint Triangles):   ,, and ,,
