Puzzle

Hints

Click a Tab to reveal the Hint.

Look at how the red and blue lines cross over each other at the tetrahedron. Note that three lines, one blue and two red, cross over the edges of the center triangle in the collapsed tetrahedron.

The missing triangle's right side connects with the top triangle's right side. You can see two lines here, one red and one blue.

The bottom side of the missing triangle connects with the bottom the left most triangle. Only a single red line passes over this edge.

Read previous hints and check which lines cross where. Do that, and the answer is yours.
