Which real-world transformations can be represented by dilations? Choose two correct answers.

A dilation changes the size of a figure by multiplying every length by the same scale factor while keeping its shape. Reducing a photograph to half its dimensions uses a scale factor of 1/2, and doubling its dimensions uses a scale factor of 2. Moving or turning a photograph changes its position or orientation, and cropping only one side changes its shape rather than dilating it.
