- A New Match Puzzle
- I have a box of matches.
- I find that I can form with them any given pair of these four regular figures, using all the matches every time.
- This, if there were eleven matches, I could form with them, as shown, the triangle and pentagon
- Of course there must be the same number of matches in every side of a figure.
- Now, what is the smallest number of matches I can have in the box?
