Issouf claims that the scale factor is One-half. Which statement about his claim is correct?
Line segments A prime B prime and A B. The distance from the center of dilation C to A prime is 2. The distance from A prime to A is 4.
He is correct because CB is 4 and C’B’ is 2. The scale factor is StartFraction C prime B prime Over C B EndFraction = StartFraction 2 Over 4 EndFraction = one-half.
He is correct because he needs to subtract 2 from each side. A reduction has a scale factor that is a fraction, so it must be One-half.
He is incorrect because it is 3. CB is actually 2 + 4 or 6. So one needs to multiply the pre-image length by 3 to get the image; 3 is the scale factor.
He is incorrect because the scale factor is One-third. CB is actually 2 + 4 = 6. CB is the pre-image, so the scale factor is StartFraction C prime B prime Over C B EndFraction = StartFraction 2 Over 6 EndFraction = one-third.
