Question

Analyzing a Scale Factor

A rectangle is dilated by a scale factor of n = 1. Which statement is true regarding the image of the dilation?

The image will be smaller than the pre-image because n = 1.
The image will be congruent to the pre-image because n = 1.
The image will be larger than the pre-image because n = 1.
The image will be a triangle because n = 1.

Answer 1

The statement that is true regarding the image of the dilation is: "the image will be congruent to the pre-image because n = 1." When an object is dilated by a scale factor of 1, it means it is not dilated at all and remains the same size and shape. Therefore, the image will be congruent to the pre-image.
