Dilations: Graph the image
Copy polygon ABCD shown on graph paper. Then draw the image of the figure after a dilation with center A by a scale factor of 2. 


Step 1. 
Draw a ray AB, extending it to the edges of the grid. 
Step 2. 
Use a ruler to locate point B' on ray AB such that AB'=2(AB). 
Step 3. 
Repeat Steps 1 and 2 for points C' and D'. Then draw polygon A'B'C'D' where A=A' 
Copy polygon PQRS shown on graph paper. Then draw the image of the figure after a dilation with center S by a scale factor of . 


Step 1. 
Draw a ray SP, extending it to the edges of the grid. 
Step 2. 
Use a ruler to locate point P' on ray SP such that SP'=. 
Step 3. 
Repeat Steps 1 and 2 for points R' and Q'. Then draw polygon P'Q'R'S' where S=S'
