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>

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
