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

Trapezoid FISH is congruent to trapezoid TOAD. Determine which sequence of transformations maps trapezoid FISH onto trapezoid TOAD.

• Reflection across x= -0.5 and translation 2 units down

• Reflection across y-axis and translation 2 units down

• Reflection across x= -1 and up 2 units

Are the two figures similar? If so, describe a sequence of transformations that maps \Delta ABC onto \Delta DEF. If not, explain why they are not similar.

• No, the scale factors are different

Gabriela draws ABCD. Next she dilates ABCD by a scale factor of 3. What is the ordered pair for B'?

Determine how to translate triangle ABC to triangle A'B'C'.

• left 2, up 9

• right 2, down 9

• Reflect over the y-axis

• Rotate 180 degrees

• Translate to the left 2 units
