Ans. To find the Points of Trisection of a line segment joining points ( A(x_1, y_1) ) and ( B(x_2, y_2) ), you divide the segment into three equal parts. The coordinates of the points of trisection, ( T_1 ) and ( T_2 ), can be calculated using the formulas: [ T_1 = left( rac{2x_1 + x_2}{3}, rac{2y_1 + y_2}{3} \right) ] [ T_2 = left( rac{x_1 + 2x_2}{3}, rac{y_1 + 2y_2}{3} \right) ]
