On page 121, the following definition of a dilation is given. A dilation (with center P and scale factor k > 0) is a motion in the plane in which the image of P is P and the image A' of any other point A is on the ray PA so that the distance PA' is k times the distance PA. Note: As before, it may be helpful to think of a dilation as acting on an object in the plane, rather than the plane itself. i) Draw the image of the below objects under a dilation with center P and scale factor 2.
