Answer the following
questions dealing with dilations and coordinate geometry.
1. 
Under a dilation, triangle
A(0,0), B(0,4), C(6,0) becomes triangle
A'(0,0), B'(0,10),
C'(15,0). What is the scale factor for this dilation? 


2.




3. 



4. 



5. 



Grab your graph paper for the following problems.
6. 

A(2,3), B(2,1),
C(1,1)
Graph triangle ABC and its image under D_{3}.
. 
Answer


7. 

Rectangle A(1,1),
B(4,1),
C(4,2), D(1,2) is similar to rectangle
A'B'C'D'.
If A'B' = 6, graph a dilation (center origin) of
rectangle ABCD showing both rectangles and state the
scale factor.
