Question

Point A (5, 1) on reflection on X- axis is mapped as A’. Also A on reflection on Y- axis is mapped as A”.
(i) Write the co-ordinates of A’.
(ii) Write the co-ordinates of A”.
(iii) Calculate the distance A’ A”.
(iv) On which coordinate axis does the middle point M of A” A’ lie?

Answer 1

(i) A' → (5, -1).
(ii) A'' → (-5, -1).

(iii) Distance A'A'' = 5 + 5 = 10.
(iv) Miles on Y-axis.
