• No because the the two objects do not match up

• No because one of the objects is upside down

• Yes, reflection across the x-axis

• No, the two images do not match up

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

• No, the scale factors are different

Are the two figures similar?  If so, describe a sequence of transformations that maps rectangle CARS onto rectangle BIKE.  If not, explain why they are not similar.

• Yes, dilation of 3 and translation right 5 units and up 3 units

• No, scale factors are not the same

Trapezoid ABCD is similar to trapezoid LMNO. Determine which sequence of transformations maps trapezoid ABCD onto trapezoid LMNO. 

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
