(ii) (3, 0)                              

(iii) (0, 0)                             

(iv) (2, -4)           

(v) (-3, -5)


2. Find the co-ordinates of the image of the following points under reflection in the origin:

(i) A (2, -5)                          

(ii) B (-5/2, -1/2)                               

(iii) C (0, 0)


3. Write the co-ordinates of the image of the following point when reflected in origin.

(i) P (6, 5)                            

(ii) Q (6, -5)                        

(iii) R (-6, 5)        

(iv) S (-6, -5)


4. A point P is reflected in the origin. Co-ordinates of its image are (2, -5). Find the co-ordinates of P.

5. Write down the coordinates of the image of the point (3, -2) when reflected in the origin.
