Question

Which real-world transformations can be represented by dilations? Select two options. 1. turning a camera to take a photograph 2. cropping a photograph to a square by cutting only one side 3. reducing a photograph to half its dimensions 4. enlarging a photograph to double the dimensions 5. moving a photograph to a different page

Answer 1

Explanation:

Answer 2

3 and 4

Explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size so here reducing a photograph to half its dimensions and enlarging a photograph to double the dimensions is dilation.

=> For dilation, we use a certain scale factor

=> In the 3rd option, scale factor is 1/2

=> In the 4th option, scale factor is 2.
