The students are to sow seeds of flowering plants on the remaining area of the plot. A 1 2 3 4 5 6 7 8 9 10 (i) Taking A as origin, find the coordinates of the vertices of the triangle. (ii) What will be the coordinates of the vertices of A PQR if C is the origin? Also calculate the areas of the triangles in these cases. What do you observe?
