Closed loop on a tetrahedron
Place a tile on each face of a [regular tetrahedron](https://en.wikipedia.org/wiki/Regular_tetrahedron) so that the arcs on the tiles form a single closed loop. You may rotate the tiles provided they align with the triangular faces of the tetrahedron. There are 4 identical tiles: [![4 triangular tiles each with an arc joining the centres of 2 of their edges][tiles]][tiles] Here is a net of a tetrahedron to arrange the tiles on: [![4 triangular faces that can fold into a regular tetrahedron][tetrahedron net]][tetrahedron net] ## Printing Each image can be opened in a separately tab (which will display the tiles at exactly the right size to place on the net) to allow printing so you can experiment or photograph your solution.
