My daughter’s project showing a proof of the Pythagorean Theorem won the “first round” of her “Math is Cool” contest. It’s a pretty cool proof - she (with supervision) used the Glowforge to laser cut AxBxC right triangles out of different colors of acrylic. Then kids can use the triangles (and a small square) to make a square of CxC, and a shape that includes AxA and BxB squares out of the same material. Since you use the same pieces for both, that shows that a^2 + b^2 = c^2!
Contest ends 1/31. Thanks! (and feel free to share widely)
