(x + 3, y + 2)
(x, y)---->
(x+2, y + 3)
(x, y)---->
(x - 2, y + 3)

Congruent figures are figures that are the SAME size and the SAME shape.
A dilation produces a congruent figure.
True
False
Dilate the figure by a scale factor of 3. What are the coordinates of the image?
A(3,3) B(6,6) C(9,3)
A'(9,9) B'(18,18) C'(27,9)
A'(6,6) B'(9,9) C'(12,6)
A'(0,0) B'(3,3) C'(6,0)
A'(1,1) B'(2,2) C'(3,1)
Does the image show a Dilation and what is the scale factor?
Yes; k = 2
Yes; k = 1/2
No, it's a translation.
No, it's a reflection.
