SF=34 gives a contraction.

−25 gives an opposite side contraction.

Explanation:

A scale factor of1 gives an image the same size.

A scale factor of more than one gives a bigger image.

A scale factor that is a proper fraction gives an image smaller than the original figure. Of the options available only 34 is less than 1, so this would give a contraction.

A negative scale factor does two things:

It places the image on the other side of the centre and inverts it.

A scale factor of −25 will:

  • Give a smaller image (a contraction)
  • On the other side of the centre
  • Invert the image.

The correct option is opposite side contraction.
