  1. Well we know that these two hypotenuses
    must be the same.
  2. This hypotenuse, and this hypotenuse
  3. were both measured using a length of the string.
  4. The length of the string is 50cm
  5. and it hasn't changed since when we created
    this triangle from the first triangle.
  6. We only change the position of the end of the string
  7. when creating a second triangle.
  8. So the length of the string didn't change
  9. so we know these two lengths must be equal.
