Pre-image  ABCD is dilated to be ​ image ​ A′B′C′D′ . The origin is the center of dilation.

What scale factor is used to create the dilation?

Notice  that

 

5A  = 5 (1,2)  = (5,10) = A'

5B  = 5 (2,2)  = (10,10) = B'

5C = 5 (2, 1)  = (10, 5)  = C'

5D = 5 (1, 1)  = (5, 5)  = D'

 

So....the scale factor  is   5

 

 

cool cool cool
