(i) Point A is reflected in y-axis to get point B.

(ii) Point B is reflected in origin to get point C.

(iii) Point C is reflected in y = 0 to get point P. Now, which of the following coincides with point P.

1. Point A

2. Point B

3. Points B and C

4. Points A and B

The point P is reflected in x = 0 to get the point P' and the point P' is reflected in y = 0 to get the point P". Which two points out of P, P' and P" are invariant under this reflection.

1. P" = P

2. P" = P'

3. P' = P

4. no-one

The point P(5, 7) is reflected to P' in x-axis and O' is the image of O (origin) in the line PP'. The co-ordinates of O' are :

1. (10, 0)

2. (0, 10)

3. (10, 10)

4. (5, 5)

The point P(x, y) is reflected in the line y = x to point P'(x', y'), then :

1. x = y

2. y' = x'

3. x = x' and y = y'

4. x = y' and y = x'
