If the center of dilation is at the origin, by what scale factor was octagon ABCDEFGH dilated?
A.) 1/2
B.) 1/4
C.) 2
D.) 4

C. 4
Look at where segment A'B' intersects, at x = 8.
Look at where segment AB intersects, at x = 2.
AB is smaller then A'B' that means the scale factor is
[tex]A'B'/AB=\frac{8}{2}=4[/tex].
Hope this helps.
