Which transformation(s) is non-rigid? Why?
Dilation, because it does not maintain the shape and size of the pre-image. The size changes (either expands or shrinks).
Describe how to move a point that is being translated by <3,-2>.
right 3, down 2
What is point A' if point A (5,2) is rotated clockwise 90°?
(2,-5)
What is A' if point A (-3,3) is reflected across the x-axis?
(-3,-3)
What is the transformation that maps ΔABC onto ΔA'B'C'? 
Reflection across the x-axis.
What is a rigid transformation? Give 3 examples.
A transformation that does not affect the size and shape of the pre-image when going to the final image. Reflection, rotation and translation.
Describe the transformation (x,y) --> (x+1,y+2).
Translate right 1, up 2.
What is B' if point B (2,-1) is rotated clockwise 180°?
(-2,1)
What is B' if point B (-3,3) is reflected across the y-axis?
(3,3)
What is the transformation that maps ΔABC onto ΔA'B'C'? 
Dilation by 1/2.
What are the dotted lines in this image called?
Lines of Symmetry
Describe the translation that maps ΔABC onto ΔA'B'C' in notation form.
(x-4, y+4)
What is C' if point C (3,4) is rotated clockwise 270°?
(-4,3)
What is C' if point C (-3,3) is reflected across the line y=x?
(3,-3)
What is the transformation that maps ΔABC onto ΔA'B'C'? 
Counter clockwise rotation 90°.
