A similarity transformation maps polygon ABCD to polygon PQRS. If the length of AB(WITH THE LINE OVER THE TOP) is 6 and the length of the corresponding side,PQ ( with the line over top) , is 12, what is the scale factor of dilation? A. 2 B. 0.5 C. -6 D. 6

Respuesta :

AB maps to PQ
  So 6 turns into 12
 
  6k = 12
  k = 12/6
  k = 2
 
So, option A which is 2 is the correct answer.
