5.4.1 Transformations - Enlargement

Enlargement – what do I need to know?

  • You need to be able to perform an enlargement (on a coordinate grid) as well as spotting and describing an enlargement when presented with one.
  • The key things with an enlargement are:
    • Scale Factor
      The scale factor is how many times every side of the image is bigger than the object
      However if the scale factor is a fraction the image will be smaller than the object
    • Centre of Enlargement
      This tells us where on the page the image is going to go but we have a bit of work to do first
      As with the other transformations in most cases it is easiest to move one vertex of the shape and draw the image from there
