Materials used were 1/2 inch gypsum board for the circle. 2x4 inch pine segments to support the back, as well as make the stand for it. Used a short half inch bolt, washers and nut to bolt the gypsum to the stand so it would turn easily. Used the “pencil on a string” trick with a tack in the middle of the gypsum board to create the circle. Used a gypsum knife to cut the circle, though any saw would probably do. Painted the gypsum white. Purchased plexiglass sheets from Home Depot, and had the squares (fronts and backs) as well as the square edges all cut with a table saw. Needed 18 pieces of plexiglass cut. It was key that they all that all of the edges be the same width, so we stacked up several pieces of plexiglass and cut them into strips all at once. It worked great. We used an arbitrary 1 inch width for all square edges. Drilled small holes in the gypsum then screwed the first three squares to the gypsum board, Screwing them in with screws, then dabbing them with silicone caulk so it wouldn’t leak. Then glued all pieces together with superglue, cutting and drilling as needed as a we went along. We added blue food coloring to the water to make it easier to see. All material was purchased from Home Depot. Lowes would have the same thing.

[@victorteeter1853]

Correction: where it states “Drilled small holes in the gypsum then screwed the first three squares to the gypsum board” should say “Drilled small holes in the PLEXIGLASS then screwed the first three squares to the gypsum board.”

This is probably the best way I've ever seen to explain the Pythagorean theorem.

[@AdamThygerson-lm1gt]

I believe this experiment is flawed because the depth of each compartment of water is diffrent and there seems to be no correlation between side length and depth of the water reservoir so this experiment is not showing the Pythagorean theorem it just show's two areas equal one larger area. Which of course is subject to the changing of the volumes of each compartment. This may be incorrect and please correct me if I am wrong, without any measurements of the compartment volumes I have to say it is wrong.

[@eduardo_fbarbosa]

This is wrong. The Pythagorean theorem talks about area, not volume

[@f.i.b3027]

​@@eduardo_fbarbosa The depth in each container is the same so the fact that it is a volume doesn't matter, they cancel out.

[@eduardo_fbarbosa]

@ yes, you’re right

[@Mohanchous]

Also, if you dropped a perpendicular from the right angle vertex to the far side of the large square, it would cut the large square into two compartments equal in area to the two smaller squares. You could then use two colors of water to show this. This would be closer to a demonstration of Euclid's proof from the Elements.

[@bradens.3125]

i wish this was demonstrated in schools, a very intuitive demonstration of truly understanding what the theorem means

[@GuaseMinas512]

And what does it mean? What did filling squares with water add to your understanding, that simply calculating the area couldn't provide?

[@shannonwilhoite9747]

I never understood this video until I looked up the meaning. The Pythagorean Theorem says that you can take the square of the two leg lengths and they will be equal to the square of the length of the hypotenuse. Thats the same thing as finding area of a square (squaring one side length). For this reason, the space that two of those smaller squares takes up should be the same as the space that the larger square takes up. a^2 + b^2 = c^2 OR area of square 1 + area of square 2 = area of square 3.

[@NowhereManForever]

***** The thing is, this is not a proof. It is merely a demonstration. Sure, I can do demonstrations of mathematical concepts all day long but it doesn't hold up in serious study.

[@TheiLame]

I think demonstrations should be shown as much as possible because they make everything easier to understand.

[@peterfireflylund]

***** This demonstration showed the meaning of a² + b² = c² -- or rather a demonstration for a specific (a,b,c)-triplet. It did not demonstrate that it holds for any other triangle and certainly not that it holds in general. And does it really make anything easier? We already knew it was about two areas that should add up to be equal to another area -- so why introduce volumes? Why, in fact, introduce an extra step just to prove that this example about volumes of water is equivalent to an example about areas, which is what we started out being interested in? Furthermore, we have good empirical evidence from the didactics of physics and chemistry to show us that demonstrations usually /hinder/ learning, at least if they are performed by the teacher. An alternative to this demonstration is to have the student measure areas (by counting squares on graph paper, for example) which is not as "cool" but something we should expect to work better.

[@TheiLame]

Peter Lund I thought for a long time how to answer since clearly my mathematical skills and some english isn't very good. You said: '' It did not demonstrate that it holds for any other triangle and certainly not that it holds in general.'' /So the same demonstration works for other angles that arent right angles, too? Im sorry for my english, maybe i didnt understand you right, please let me know./ But i guess you are right about the fact that extra volumes can actually make it more confusing - i did not even think about it. I guess i really was amazed by the fact that it just looked ''cool''. Although let me say this: It should not be a big problem if it was explained why and how volumes also work on this. (/although you just said that this demonstration works for every triangle? Please let me know if i misunderstood you/) It may add confusion or extra knowledge, depends how well it is explained. And also the ''coolness' adds ''interest'' which could help a lot in the progress of learning. But of course, getting down to the core of it by - lets use your example - counting squares on graph paper, would definitely be the real experience understanding it.

[@isobelgray2527]

Captivating truely. The special effects really brought this piece together. There would need to be more dialogue however from the budget and the materials in which the director was given this truely was a film for the ages. Overall the filming and decision to have the camera slightly off centred showed true emotion of all the characters. While the plot was confusing to start with the subtle hints throughout made it clear to the viewer the main characters true intentions and reasons for their actions. This film got very inappropriate towards the end and I would not recommend watching it with younger audiences however if you wish to see a very well thought out and beautiful piece of art I highly recommend this video. We truely did learn the true meaning of friendship and the ups and downs of high school football. Thank you so much for producing this film that admittedly did make me shed a few tears.

@buried2 It is a great illustration/demonstration, but it isn't an actual proof -- just in case any students try to use this as a "proof" in geometry class. Also, considering that water is three-dimensional, it isn't really a direct demonstration of the Pythagorean Theorem. We are probably to assume that, as long as the triangles are in the correct proportion, the depth of the water is constant for all three triangles.

[@123mathtutorabc4]

As stated above, it's not a proof but it's empirical evidence of the Pythagorean theorem for that specific right triangle. Even saying that isn't completely accurate if one wants to be pedantic since the demonstration is based on equivalent volumes and not areas.

[@123mathtutorabc4]

IMO, Bhaskara's proof of the Pythagorean theorem is the simplest to understand for those who do not have experience dealing with proofs.

[@skybirdprojects5489]

This works because each area is equal to the squared length of each side of the triangle. Wheres the hypotenuse is the equal to root of the sum of the squares when doing a triangle, this demonstration is actually just the sum of the squares because the root is squared and is thus cancled out.

So: S3*S3*H3 = S2*S2*H2 + S1*S1*H1 can be written S3*S3*H = S2*S2*H+S1*S1*H can be written S3*S3*H=((S2*S2)+(S1*S1))*H So the H goes away from both sides (S3*S3)=(S2*S2)+(S1*S1)

For the confused people: 1. Get a piece of paper and a ruler to make straight lines and to exemplify the techniques I will list. 2. Squaring/by common name, Squared: Squaring is symbolized by a little 2 to the top right of your number. Squared means 2x2 or and other number multiplied by itself. For example: 2²/2 x 2. 3. The Pythagorean theorem trick: is too (on a calculator or in head) square both legs (two sides the make the right angle) and combine them. After doing so, square the hypotenuse (the one that slants to connect the 2 ends of the right angle) and find the square root. If the two answers (one from the combined legs are equivalent and the hypotenuse's square root) are equivalent the the triangle is a right triangle. You're welcome. 4. Confusion on the squares: you can break down a triangle easily...there are 3 sides (which are in measurements) and each one needs to be squared, for example: 2 inches TIMES 2 inches, take one of those 2 inches and put it into the height of the square, take the other and make it into the length of the square. BOOM! that's how they got squares. You're welcome. 5. The legs of a right triangle are the ones connect to the little square in the corner, this represents that there is a 90 degree angle from leg to leg. 6. The hypotenuse is the slanting line that connects the two ends of the right angle, this will also be the longest side of the right triangle. 7. The Water Demo represents the trick, the squares are just the measurements of the lines squared. So if those L squares (the squares representing the legs) are filled with water than we can see if they are equal (when combined) to the hypotenuse by transferring the water. Now you have Squaring, Right triangles, Mathematically Creating a Square, and Pythagorean theorem trick consolidated into 7 short paragraphs. You're welcome.
