Use a ruler or measuring tape to compare the image and the original figure
Check whether corresponding lengths are multiplied by the same scale factor
Verify that corresponding angles stay the same
Confirm that the shape remains similar after resizing
Compare side lengths to see if each one is scaled consistently
Check the center of dilation if one is given
Measure the distance from the center to corresponding points before and after dilation
Make sure all points move along lines passing through the center of dilation
Determine whether the image is an enlargement or a reduction
Calculate the scale factor by dividing image length by original length
Confirm that the scale factor is the same for all corresponding sides
Use coordinate rules if the figure is on a graph
Check whether each coordinate is multiplied by the same factor from the center
Compare the orientation of the figure to see if it is preserved
Verify that parallel lines remain parallel after dilation
