Lesson#9 Question No. 27 Q.27. One vertex of a parallelogram is (1,4); the diagonals intersect at (2,1) and the sides have slopes 1 and -1/7. Find the other three vertices. Math Ex. 4.3 Part 09 Solution: referred to diagram, There is a parallelogram.|Give information is shown. Let B(x1, y1) , C(x2, y2) and D(x3, y3) are unknown vertices. As diagonals of a parallelogram bisect each other so M(2, 1) is midpoint of both diagonals. Midpoint of AC = (x2+1/2, y2+4/2) ...
