I got this puzzle and would like to ask for your opinion. Is it possible to divide a rectangle into 3 identical triangles? If yes, how ? I couldn't do it. If no, why? Thanks. (this is a puzzle for fun!).

How many times can we cut the rectangle and rearrange the pieces ? – Donald Splutterwit Sep 12 '17 at 21:18

This Samuel Maltby paper shows that it is impossible to divide a rectangle into 3 identical pieces that are not rectangular.

Nope! In fact, we can say much more: Monsky's theorem states that you can't divide a parallelogram into an odd number of triangles of equal area. The nice thing about this result is that it applies to triangles having arbitrary angles.
