Question

Triangle ACD is dilated about the origin.10D876-54DсА-7-6-54-3-2-10231-2Which is most likely the scale factor?23okay

Answer 1

The scale factor can be obtained by ratio of sides lengths of new figure to the corresponding side of old figure.

From the graph it can be observed that measure of one side of triangle ACD is,

CD = 2 units

The measure of side C'D' of triangle A'C'D' is C'D' = 6.

The scale factor is,

`\begin{gathered} s=(C^(\prime)D^(\prime))/(CD) \\ =(6)/(2) \\ =3 \end{gathered}`

So scale factor is 3.
