Extension work and Homework task

If you have completed the first 2 tasks then begin your research for your homework task. go to google and search for 'tv size dimensions' and then look at images. I want you to have a look at how their sizes are measured and notice something that is similar to what we have been looking at with right angled triangles. Do you see the link? For homework I want you to meausre your TV screen or even a computer screen and give me its diagonal dimension. Firstly, I want you to measure the sides then calculate the hypotenuse. Secondly, I want you to measure with your ruler or measuring tape the diagonal length. With your two measurements, see how close your answers are and we will discuss your findings next lesson.
