Transformations Similar Figures Scale Factors

Mr. Rogers produces a street sign graphic on his computer that is 4 inches by 5 inches. He enlarges the graphic by a scale factor of 3 to print. Then Mr. Rogers enlarges the image by a scale factor of 4 before sending it to the machinist.

Are the enlarged graphics similar to the original? 

• YES

• NO
