What type of dilation occurs with a scale factor of 1 or 100%

Answer :

Solution:

Concept:

The center of dilation is a fixed point in the plane. If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). If the scale factor is 1, the figure and the image are congruent.

Hence,

No dilation occurs because the figure and the image are congruent.
