Figure undergoes a sequence of transformation that include dilutions. The figure and its final image are congruent explain how.

Only a dilation would change the shape's dimensions-- any type of shift would simply relocate the shape. We must only prove that dilation do not change the concurrency. Dilations, by definition scale on object-- if you dilate it by 2, the second image will be exactly twice the original. This is true for any legal dilation.
