Describing effects of transformations

Which rule shows a reflection over the x axis, followed by a translation right 2, down 1?

• T<2,-1> ^o R_{x axis} 
• T<-2,1> ^o R_{x axis} 
•  R_{x axis} ^o T<-2,1> 
•  R_{x axis} ^o T<2,-1>

What sequence of transformations will get you from shape BCD to shape B"C"D" in two steps?

• Rotation, then Rotation
• Rotation, then Dilation
• Reflection, then Rotation
• Translation, then Reflection

This is the last time we will do composition of transformations (outside of what you see on your test). How confidence are you on rigid motions and their compositions?

• WOOT! I am the BEST as rigid motions!

• Confident

• Could be doin' better

• Could be doin' worse

• Not confident at all

What is the third step in the composition?

R_D,90(r_y-axis(T_2,-3(triangle ABC)))

• Translation up 2, left 3

• Translation right 2, down 3

• Draw triangle ABC

• Rotate about point D 90 degrees

• Reflect over y-axis

Name the series of transformations that maps ABC (the pre-image) onto DEF (the image).

The dotted triangle is the transformation between ABC and DEF.

• reflect over x-axis, then translate left 6 up 1

• reflect over y-axis, then translate down 6 left 1

• translate right 6 down 1, then reflect over x-axis

• rotate 90 clockwise, then reflect over y-axis
