Question

How was ABCDEFGH transformed to A'B'C'D'E'F'G'H'?

A) dilated by a scale factor of 1/3
B) dilated by a scale factor of 1/2
C) dilated by a scale factor of 2
D) dilated by a scale factor of 3

Answer 1

its D on USA test prep

Answer 2

so ur going from a smaller shape to a larger shape....means the scale factor is more then 1. The scale factor is the number that u multiply the original shape by to get the other shape.

so lets look at DE...it is 2.....and D'E' is 6

so 2 * x = 6...with ur scale factor being x
2x = 6
x = 6/2
x = 3.....so the scale factor is 3....because multiplying the original shape by 3, gives u the other shape
