Question

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

Answer 1

C is the answer for this one

Answer 2

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

`A'B'/AB=(8)/(2)=4`.

Hope this helps.
