Question 3
3.
(Level 2) Is Figure 1 similar to Figure 2 ? Explain.
Question 4
4.

Question 5
5.
(Level 3) What are the coordinates of the image of \vartriangleABC after a dilation with center (0, 0) and a scale factor of 3?
Question 6
6.
(Level 3) \vartriangleRST has vertices R(0, 0), S(6, 3), T(3, -3). \vartriangleR'S'T' is the image of \vartriangleRST after a dilation with center (0, 0) and a scale factor \frac{1}{3} . What are the coordinates of point S' ?
