what is the difference between an
isometric transformation and one that is not isometric? give examples of least
two isometric transformations and at least one non-isometric
transformation.

The correct answer is:

An isometric transformation is one in which the shape and size of the figure does not change. A non-isometric transformation is one in which the figure changes size or shape.

Explanation:

An isometry is defined as a transformation that maintains congruence; this means the image is the same shape and size as the pre-image. It also means that if a transformation is not an isometry, then congruence is not maintained.

Reflections, rotations, and translations are all examples of isometries. Reflections give us a mirror image of the figure; rotations turn the figure; and translations slide the figure.

Dilations are examples of transformations that are not isometries. A dilation stretches or shrinks the image, so it changes the size.
