Question

If the points (a, -11),(5, b), (2, 15) and (1,
1) are the vertices of a parallelogram taken in
order, then the values of a and b are
(a) a = 4, b=-3 (b) a=-4, b=3
(c) a = -4, b= -3 (d) a = 4, b = 3​

Answer 1

If the points (a, -11),(5, b), (2, 15) and (1,

If the points (a, -11),(5, b), (2, 15) and (1,1) are the vertices of a parallelogram taken in

If the points (a, -11),(5, b), (2, 15) and (1,1) are the vertices of a parallelogram taken inorder, then the values of a and b are

If the points (a, -11),(5, b), (2, 15) and (1,1) are the vertices of a parallelogram taken inorder, then the values of a and b are(a) a = 4, b=-3 (b) a=-4, b=3

If the points (a, -11),(5, b), (2, 15) and (1,1) are the vertices of a parallelogram taken inorder, then the values of a and b are(a) a = 4, b=-3 (b) a=-4, b=3(c) a = -4, b= -3 (d) a = 4, b = 3
