Explain how to use the figure below and a sequence of similarity transformations to prove that all circles are similar.

1) Move the center of CIRCLE A to the center of CIRCLE B to make these circles concentric.
2) A dilation is needed. This is to increase the size of circle A to coincide with circle B. A value that when multiplied by r will create s is needed.
The scale factor, x, to increase circle A :  r * x = s  --->   x = s/r        3) A translation then a dilation with scale factor, s/r, will map one circle onto the other, thus proving that the circles are similar.
