What are the common mistakes in Enlargements Negative Scale Factor?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

• Drops a negative sign, treating a negative value as positive

  Used the size of the scale factor but ignored its negative sign, so the image was not rotated 180° through the centre as it should be.

• Confuses a positive and negative scale factor

  Using the positive version of the scale factor keeps the image on the same side as the object - with a negative scale factor, the image must be on the opposite side of the centre.

• Uses the linear scale factor directly as the area scale factor instead of squaring it

  Uses the linear scale factor -2 directly as the area scale factor instead of squaring it, giving -2 instead of 4.
