Ray's Matchstick Puzzler
RAY: This puzzler is from the matchstick series. Imagine, if you will, that you have four matchsticks of equal length. From those, you can easily make a square.
At each of the vertices, there is a right angle, or a ninety-degree angle, so there are four right angles.
TOM: I'm with you!
RAY: Now, using those same four matchsticks, make not 4 but 16 ninety-degree angles.
You might say, "Can I use the third dimension?" You can use any dimension you want.
I should mention, you are not allowed to fold, bend, break staple, or mutilate the matches in any other way.
TOM: Can you use mirrors?
RAY: No, but that shows you're on the right track.
Think you know? Drop Ray a note!
