Which of the following describes a figure and its image under a dilation ?A. They are equivalent.B. They are congruentC. They are similar

Sagot :

A dilation is a transformation that produces a change of size of an image without changin its shape.

To transform the image, the measures or coordinates are multiplied by a scale factor "k"

If the scale factor is k>1 the resulting transformation is an enlargement. The image will be larger than the original one.

If the scale factor is k<1 the resulting transformation is a stretch. The image will be smaller than the original one.

In both cases, as mentioned before, the shape of the image doesn't change after the dilation, so the resulting image will be similar to the original one.

The correct option is C.
