Practice the questions given in the worksheet on reflection in different axis. The questions are based on how to find the coordinates of the image of a point under reflection in different axis.
1. The point M (2, 9) is reflected in the xaxis; find the coordinates of the image M’. This M' is further reflected in yaxis. Find the soordinates of the image M''. Also, find the image of M (2, 9) in the origin.
2. If point P (2, 7) is reflected in the origin, then find the coordinates of the image P’. It is again reflected in yaxis. Find the image of P' i.e., P''
3. Write the reflection in different axis when the coordinates of the object and image are known.
Object Image
(i) P (5, 2) P'
(5,2)
(ii) Q (1, 3) Q' (1, 3)
(iii) R (2, 4) R'
(2, 4)
(iv) S (0, 3) S' (0, 3)
4. Point P (h, k) is reflected in xaxis and point P' is obtained as the image of P. now P' is reflected in yaxis the image of P’ is obtained as P’’. Find the coordinates of P''.
5. If point M (3, 8) is reflected in origin, then find the coordinate of the image M'. It is again reflected in yaxis. Find the image of M' i.e., M''.
