> Do kids still learn Pythagorean Theorem? Triangles? <
I’m a retired public high school teacher. When I first started teaching 30 some years ago, I taught math. Geometry was its own separate course. And it was based on formal proofs. Given this, prove that.
It was a great course, as it taught logical and organized thinking. So naturally the school board got rid of it. Near the end of my career, I taught physics. And we used the Pythagorean Theorem often. It has many practical applications.
I got ChapGPT to give me a nice proof of the Pythagorean Theorem in n-dimensional Euclidian Space but I found a minor error in it which he accepted gracefully and apologized for.
