Practice 1.2 - Properties of Rigid & Non-Rigid Transformations

• a translation of 3 units left and 3 units down

• a counterclockwise rotation of 180^o around D. 

• a reflection in the y-axis

• a dilation with a scale factor of 3 centered at the origin

The diagram shows ABC mapped onto DEF by a reflection over y=x. If m<A=34^o, m<B=40^o, and m<C=106^o, find m<F.

• 40^o

• 34^o

• 106^o

• 74^o
