The object and its image are congruent.

A translation of 4 units to the right followed by a dilation of a factor of 2
congruent figure
The image and pre-image are congruent.
isometry
Dilation - the image created is not congruent to the pre-image
The object and its image are congruent.
A dilation (or scaling) is a transformation that does not always result in an image that is congruent to the original figure. While translations, rotations, and reflections always produce congruent figures, dilations change the size of the figure, which means the image may be similar to, but not congruent with, the original figure.
Congruent in all three cases.
An enlargement but the angle sizes will remain the same.
An enlargement transformation
An isometry is a transformation in which the original figure and its image are congruent. Shape remains constant as size increases.
The transformation process is an 'enlargement'
