how, in simple terms, can we prove the Pythagorean Theorem?
Question 147189: I need an explanation of why the Pythatgorean theorem can be used only for right triangles that an 8th grader can understand. What I know is that the Pythagorean Theorem is a special case of the Law of Cosines where the Cos(c) is equal to zero which only happens when c=90 degrees. But I don’t think an 8th grader has had the law of cosines yet. I’d really appreciate some help with this. Thanks.
