      This attached document is a lesson that explores the differing TV sizes:

      16:9 (widescreen)

      4:3 (standard)

      21:9 (cinema)

      Students are given one width and asked to find the length, then they are asked to use pythagorean theorem to find the diagonal–which is how TV sizes are defined (corner to corner)
