MATHS - Trigonometry -Pythagoras

The video tutorial introduces Pythagoras' theorem using an analogy of gold squares, explaining that the square on the hypotenuse of a right angle triangle is equal to the sum of the squares on the other two sides. It demonstrates how to use the theorem to find the length of a side when the other two are known, with examples for both hypotenuse and a shorter side. The video concludes by summarizing the key points and emphasizing the theorem's application to right angle triangles.
