Make some Space for the small Triangle?

Today i got a packing puzzle for you, it’s called triangle plus, and the task is to fit this little triangle here. This tiny little thing somewhere inside together with the other pieces – and you can see it’s packed, not too tight. There is a gap here. So it’s clear: this gap will later be used to fit this inside. If you look at the pieces, i mean this is somehow kind of hard to imagine how this should fit inside yeah.

How can these be rearranged actually, and the solution is also kind of surprising from my point of view, because you need to take all the triangles first, you put all of them here on this side like so, and on the other side, you put the remaining pieces, Like one here of course, one down here and then you can see here the remaining space for the last piece, the triangle to fit in
