Plot the points A(2,9), B(-1,3) and C(6,3) on a graph paer.On the same graph paper,draw the locus of point A so that the area of △ ABC remains the same as A moves.
Steps of construction:
i) Plot the given points on graph paper.
ii) Join AB, BC and AC.
iii) Draw a line parallel to BC at A and mark it as CD.
CD is the required locus of point A where area of triangle ABC remains same on moving point A.
