The vertices of a triangle are A(2,5), B(1,2), and C(3, 1). Find the coordinates of the image after the transformations given.
7. Reflect in the y-axis.
8. Rotate 90° clockwise about the origin.
9. Reflect in the x-axis, and then rotate 90° counterclockwise about the origin. Chapter 2 test
10. Dilate with respect to the origin using a scale factor of 2. Then translate
2 units left and 1 unit up.
11. In a coordinate plane, draw Rectangle A: ( 4,4),(0,4), (0,2), ( 4, 2);
Rectangle B: ( 2, 2), (0, 2), (0,1),( 2, 1); and Rectangle C: ( 6, 6), (0,6),
(0,3), ( 6,3). Which figures are similar? Explain your reasoning.
12. Translate a point (x, y) 3 units left and 5 units up. Then translate the image
5 units right and 2 units up. What are the coordinates of the point after
the translations?

13. The two figures are similar. (a) Find the value of x.
(b) l'ind the values of the ratios (red to blue) of the 14
perimeters and of the areas.
14. A wide-screen television measures 36 inches by 54 inches. A movie theater
screen measures 42 feet by 63 feet. Are the screens similar? Explain.
