Transformations Test
You can enter points with or without brackets and spaces, but please use commas.
For example, points can be entered in any of these ways:  (3, -5)   (3,-5)   3, -5   3,-5
Enter vectors with or without square/round brackets. Use CW and CCW for 'clockwise' and 'counterclockwise'
1. If the point (6, -15) is reflected in the X axis, it becomes:       

2. If the point (-4, 30) is reflected in the Y axis, it becomes:      

3. If the point (-31, 12) is rotated 90° counterclockwise around (0, 0), it becomes:    

4. If the point (9, -13) is rotated 90° clockwise around (0, 0), it becomes the point:   

5. If the point (9, -10) is rotated 180° counterclockwise around (0, 0), it becomes:    

6. If the point (15, -10) is translated according to the vector [5, 25], it becomes:      

7. If the point  (-8, 12) is translated according to the vector (9, 8), it becomes:        

8. The point (-8, 16) is reflected to (-8, -16). It was reflected in the    axis.

9. The point (4, 7) is rotated to (-7, 4). It was rotated   degrees in a    direction.

10. The point (3, -10) is reflected in the X axis, and then rotated by 180° clockwise.  It becomes:   

11. The point (4, 8) is rotated by 90° CW, and then translated using the vector [2, -8]. It becomes:

12. The only transformation that changes an object's size is a  

13. The characteristic of an object that is not changed by any of the transformations is
