What is Dilation?

  • Dilation, as a type of transformation, is the enlargement or reduction of a shape to create a new image which is similar to the original image.
  • If the scale factor is a whole number, it means it's an enlargement, if fraction, it means it is a reduction.

Given that the scale factor of dilation is 4, and PR is 3.

Therefore:

P'R' = 4(PR)

P'R' = 4(3)

P'R' = 12 units.

Therefore, using the dilation rule, the length of P'R' is: C. 12 units.
