I don't own the rights to this video. For educational purposes only. Just to show a 'new' theorem about isosceles triangles: "The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side". Funny thing: Spanish translation says the Pythagorean Theorem correctly (v=6h5xwetKbGI)
