### 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.

I'm not good at visualising things, so I don't know if MathsIsFun's solution works. Here's mine.

Why did the vector cross the road?
It wanted to be normal.

No! It doesn't show on the pink background.

### Re: Matchstick Puzzler

I hope I do this right, I am looking for the history and origin of the matchstick puzzle. Does anyone know where I might find this information?
