Question
A(2,2) and B(5,5) are the vertices of a figure which is symmetrical about xaxis. Complete the figure and give its geometrical name.
Solution
Steps of construction:
(i) Plot the point A and B on the graph.
(ii) Point symmetric to A(2,2) about x-axis is C(2,-2)
(iii) Point symmetric to B(5,5) about x-axis is 0(5,-5)
(iv) Join AB, AC, CD, BD.
The figure formed is a trapezium.
