Question

Match the pre-image, and its clockwise rotation, with the coordinates of its image. 1. (5, 2); 90° (-2, -5) 2. (5, 2); 180° (2, -5) 3. (5, 2); 270° (-2, 5) 4. (-5, 2); 90° (5, 2) 5. (-5, 2); 180° (-5, -2) 6. (-5, 2); 270° (2, 5) 7. (-2, 5); 90° (-5, 2) 8. (5, -2); 180° (5, -2)

Answer 1

(2,5) = (-5,2); 90°

(2,-5) = (5,2); 90°

(-2,-5) = (-5,2); 270°

(5,-2) = (-5,2); 180°

(-2,5) = (5,2); 270°

(5,2) = (-2,5); 90°

(-5,2) = (5,-2); 180°

(-5,-2) = (5,2); 180°

Each 90° clockwise turn takes a point (x,y) and transforms it to (y,-x). For a 180° turn you would do this process twice in a row; for a 270° turn, three times in a row.

Hope this helps!

Answer 2

1. (2,-5)
2. (-5,-2)
3. (-2,5)
4. (2,5)
5. (5,-2)
6. (-2,-5)
7. (5,2)
8. (-5,2)

Each 90° clockwise turn takes a point (x,y) and transforms it to (y,-x). For a 180° turn you would do this process twice in a row; for a 270° turn, three times in a row.
