Question

ABCD is a parallelogram where A(x, y). B(5, 8), C(4, 7) and D(2, -4). Find :
(i) co-ordinates of A
(ii) equation of diagonal BD.

Answer 1

Answer:

diagonals of a parallelogram biset each other so the point at which they meet becomes the mid point and then u can find it by the coordinates of B and D then u can similarly find the coordinates of A
