Pythagorean Theorem Puzzle #3

thingiverse

I found three videos of visual proofs of the Pythagorean Theorem which I decided to use with my classes. I like these videos because they are strictly visual, no audio explanation. Once my students figure out how the proofs work, they have to explain them either in writing or on video. I created this and two other puzzles to go along with these videos. The video for this puzzle can be found at https://youtu.be/LyGmcLSvJg8. Instructions Everything is ready to print. I made separate files so parts could be printed the same colors as in the video. I also shrank the puzzle pieces to 97% so they would fit better in the puzzle frame. I based all three puzzles on a 3 cm by 4 cm by 5 cm right triangle so many of the pieces are interchangeable between puzzles. The only downside is that the videos don't use the same size right triangle so the puzzles look a little different. This puzzle has a few more pieces than my other Pythagorean puzzles. There are extra triangles as well as two frame pieces that fit together (had too much trouble trying to print it as a single piece with my size print bed).
