Answer: C) center C and scale factor 2
Step-by-step explanation:
Since, The center of a dilation is a fixed point in the plane about which all points are expanded or contracted.
Therefore, By the given diagram we can say that the image is dilated along the point C.
⇒ C is the center of the dilation.
Since, for the given diagram the scale factor of dilation = [tex]\frac{C'A'}{CA}[/tex] = [tex]\frac{10}{5} = 2[/tex]
Thus, the scale factor is 2.
Therefore, Option C is correct.
