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. Join AB and A’ B’ and find if AB = A’ B’?
उत्तर
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’.
