The triangle formed by Marinette, Kagami and Luka forms the triangular "base" of the pyramid, with Adrien at the "apex"; the "three sides" of the pyramid are the three triangles combining Adrien with two of the other three people. The six edges of the pyramid (the three sides of the base, plus the three edges leading up to Adrien — all the black lines) are the six "ships". Every person can be paired with all of the other three (separately; otherwise it's a ménage-à-quatre). The formal name for the shape is a "tetrahedron".
