GCSE Secondary Maths Age 13-17 - Algebra: Pythagorous Theorem - Explained

The video tutorial explains how to prove that the area of a square formed by four right-angled triangles is equal to the sum of the squares of the two shorter sides of the triangle. The teacher uses Pythagoras' theorem to demonstrate this relationship, showing that the area of the square ABCD is equal to X^2 + Y^2. The tutorial also discusses the allocation of marks for the proof, emphasizing the importance of understanding the connection between the triangle's hypotenuse and the square's area.
