The length of a line in the image divided by the length of the corresponding line in the pre-image

Multiplying the corresponding sides of the pre-image and image

Dividing the corresponding sides of the pre-image and image

Finding the ratio of the corresponding angles of the pre-image and image

With the center of dilation at the origin, compare the coordinates of a vertex point on the image to its corresponding point on the pre-image.

Calculate the ratio of the lengths of two corresponding sides in the pre-image and image.

Measure the length of the longest side of the pre-image and image, and divide the length of the image by the length of the pre-image.

Subtract the coordinates of the pre-image from the coordinates of the image and divide the difference by the length of the pre-image.
