Question 10

Q10) Mark points A (4, 5) and B (- 5, 4) on a graph paper. Find A’, the image of A in x-axis and B’, the image of B in x-axis. Mark A’ and B’ also on the same graph paper.

(ii) Join AB and A’ B’ and find if AB = A’ B’ ?

Solution:

The given points :

A (4, 5) and B (- 5, 4) have been marked on the graph.

The image of A in x-axis A (4, – 5) and image of B in x-axis is B’ (-5, -4) which have been also plotted on the same graph.

AB and A’ B’ are joined. We see that AB = A’ B’.
