Tripling the square is a problem much simpler than that of doubling the cube ... 🤔 Here's a straightforward geometrical construction. #ProofWithoutWords Style inspired by "Idan Tal" (@MagicPi2) Credits: #Pythagoras, #Euclid, #paolozellini
ははぁ，言われてみれば当たり前だけど，こんなこと気付きもしなかったよ．メモメモ．(^^;; 初等幾何学にも面白い話題はあふれてるねぇ． #初等幾何学 #ProofWithoutWords #VisualProof
There's a proof that avoids the "arithmetic" completely, and can be called a #proofwithoutwords (taken from cut-the-knot.org/proofs/sq_root…)

Teaching geometric series this fall? Here is a compilation video of 9 geometric series dissection proofs: youtu.be/gN4EFwF5Hro #proofwithoutwords #math
Follow up to last week's animated #proofwithoutwords. What's the alternating sum of triangular numbers starting with an odd indexed triangular num? Check out this proof (adapted from Roger Nelsen): youtu.be/dRa3ItqEZwM #math
Visualizing the sum of odd squares (based on proof from Roger Nelsen) : youtu.be/WKxoi2i0EaE Can you see other sums that permit this summing technique? #math #proofwithoutwords @manim_community
New compilation: the right triangle theorem (better known as Pythagorean theorem)! Here are my ten fave visual proofs of the classic fact known for over 4000 years. Please check them out and share with math lovers: youtu.be/o2mbN452ywA #math #proofwithoutwords #visualproof
My animation of one of the oldest visual geometric sum dissections is this one for general ratio 0<(1-r)<1 and first term r in a square from Warren Page: youtu.be/KIoVix50V-k?si… #math #proofwithoutwords #visualproof
Animated one of my first published proofs without words: a generalization of one by Nelsen. Here you can find the sum of reciprocals of any column in Pascal’s triangle: youtu.be/moxeqJx2YsY?si… #math #proofwithoutwords
New animation today : Jordan’s inequality based on Feng Yuefeng’s proof without words - youtu.be/4BP_BJjOet0?si… #proofwithoutwords #math #visualproof
Happy Pi approximation day. Here’s an animation of two different Machin like formulas based on a visual proof by Roger Nelsen. Hope you like it! youtu.be/4edCTcA0mTg #pi #math #proofwithoutwords #PiDay @manim_community
