# Math puzzler: can you make a rectangle with one cut?

wait, whatās wrong with just cutting it horizontally through the middle?

Thatās what I came up with too.

Havenāt watched the video, but donāt these work? (shoddy MS Paint work notwithstanding)

I cut off the whole left side, rotated it 90 degrees, and sat it on top. Also a rectangle. (edit: @daneel had not posted when I wrote it!!)

Tangrams are where it is at

Itās interesting that there are at least three solutions. I chose a different one from the author of the video. Yet this fact was not addressed.

I agree. This āpuzzleā looks incredibly simple.

I get the impression that thereās an unstated assumption in the original problem. While it challenges you to ācut the shape into two pieces, using all the area, that can form a rectangleā, what they actually appear to mean is ācut the shape into two pieces, using all the area, that can form a rectangle [without rotating the resultant pieces]ā

(Though daneelās second solution still appears to work even then.)

I am beginning to think we are not the target audienceā¦

Very annoying. Whether these āsolutionsā work or not depends on the relative edge sizesā¦ and the author doesnāt supply those sizes.

This puzzle needed a Facebook-like ā93% canāt do it!ā sub-headline.

I do not see any math.

Okay, Iām going to be the jerk and just say it: that was stupidly easy.

yeah, I came up with a different solution, and I donāt think I would have come up with their solution because of the BB headline including āone cutā which I took to mean one straight cutā¦

That was my feeling. I saw both of @daneelās solutions, but I was pretty sure that whatever answer I came up with it would be disallowed because I wasnāt doing the kind of ālateral thinkingā that the puzzle-maker wanted me to.

Stupid-easy is right. I was so sure that the first solution I thought of (which everyone else also got) was way too obvious to be the right one, so I spent a lot of time overthinking it.
Then it just turns out to be something that he probably copied from the back of Highlights Magazine.

I, too, thought it was easy-peasy. But, racked with self doubt, I rushed to the Polygon Outlet and bought a fresh new rectangle, just to be safe.

Is it still buy 12 polygons and get the 13th for just one quatloo?

For newcomers, yes.
