4. When dilating a figure you need to have a scale factor. For our first dilation use a scale factor of 2.

5. A(4, 2)  A’(4  2, 2  2)  A’(8, 4) B(2, 0)  B’(2  2, 0  2)  B’(4, 0) C(6, -6)  C’(6  2, -6  2)  C’(__, __) D(0, -4)  E(-6, -6)  F(-2, 0)  G(-4, 2)  H(0, 4) 

6. Graph: A’(8, 4) B’(4, 0) C’(12, -12) D’(0, -8) E’(-12, -12) F’(-4, 0) G’(-8, 4) H’(0, 8)

8. Now on your graph paper calculate the coordinates for a dilation with a scale factor of 0.5.

9. A(4, 2) B(2, 0) C(6, -6) D(0, -4) E(-6, -6) F(-2, 0) G(-4, 2) H(0, 4) Here are the original points…

10. Remember to label each point with a double prime. Example: A’’
