Dilation is the type of change that changes the size of the image and has a scale factor. Which measures how large or small a picture is and is also called a scalar factor. You can determine the scale factor by starting with ΔABC, and then draw the dilation picture of the triangle with the middle at the origin and a scale factor of two. On the other hand, notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation also has a scale factor 2, multiply by 2.
