Question

Scale factor is 6/5 is the dilation an enlargement, reduction or congruence transformation? *

Answer 1

Enlargement transformation

Explanation:

A dilation is a transformation which produces an image of the same shape as the original, but may/may not be of the same size. A dilation could be an enlargement, reduction or a congruence.

The following rule applies(given the scale factor k)

• If k > 1, there is an enlargement.

• If 0 < k < 1, there is a reduction.

• If k = 1, there is a congruence.

therefore, since k=6/5=1.2>1, there is an enlargement transformation
