How do you add this small triangle to the puzzle? We can see that there is no extra space in the puzzle to place a small triangle. It seems that this is an impossible task. But the small triangle can indeed be added to the puzzle. Let's try it together. When arranging the puzzle pieces, try to leave no extra space between the pieces. In the end, you will find that there is really an extra space for the small triangle, which can be put in. It is really amazing. Do you know the principle?

the difference in space is in the gaps of the pieces.

Idk but there seems to be a difference in height in some pieces from the way the edges look from this angle, maybe some slide under each other? Idk 🤷‍♂️🤷‍♂️🤷‍♂️
