The short clip demonstrates the theory of Pythagoras by showing how to calculate the Hypotenuse of a right-angled triangle and by using numbers it proves that the triangle is right angled. The clip progresses to show the practical applications of Pythagoras by calculating the height at which a ladder against a wall reaches, and solving the problem of what size TV will fit in a particular space.
Teachers can use the video clip to demonstrate how to apply Pythagoras and help pupils solve potential exam questions. The learners could be arranged in a carousel arrangement; where they tackle exam questions with different skills such as calculating the shorter side, and proving that a triangle is right angled. Using the video clip as support, Pythagoras lends to a variety of practical solutions. So we could place learners in groups of 3 and take pictures around the school; where they would have to solve problems using Pythagoras. The learners could feedback in a presentation format to the class.
This clip will be relevant for teaching Maths. This topic appears in OCR, Edexcel, AQA, WJEC KS4/GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 5 and Higher in Scotland.
