Pythagorean Theorem visual "Proofs Without Words"
Visual proofs of the Pythagorean Theorem are nothing new. These are simply my attempts at making a few of my favorites in GeoGebra.
Proof A
Proof B
A bit of a variation on Proof A above.
Drag two vertices to resize/reshape the right triangle.
Either press play button or drag slider to animate the visual "proof."
Proof C
A web search of "Pythagorean Theorem water demo" will yield video/gifs of physical models of water passing between square chambers.
Drag vertices to resize/reshape the right triangle..
Either press play button or drag slider to animate the visual "proof."
Proof D
A bit of a variation on Proof A above.
Drag two vertices to resize/reshape the right triangle with lengths a, b, and c.
Either press play button or drag slider to animate the visual "proof."
