Two circles have the same center. Circle P has a radius of p units. Circle Q has a radius of q units. Which dilation could be used to prove that circles P and Q are similar?

 

Dilate circle Q by a scale factor of p × q .

Dilate circle P by a scale factor of p/q.

Dilate circle P by a scale factor of p × q .

Dilate circle Q by a scale factor of p/q.

Dilate circle Q by a scale factor of p/q.

 

To see this.....let the radius of P = 6   and the radius of Q = 3

 

Then.....dilating Q  we  get the new radius of   3 * 6/3  =  6 = the same radius as P
