Join Folding Tabs

I have a structure made of triangles. There are enough folding tabs for each triangle to have three. However, I am not sure how to join the triangles to their respective folding tabs.

Yes and thank you, but is there a reason why the folding tabs unfold this way and not from each triangle?
