Question

If the points A(1 -2) B(2 3) C(a 2) and D(-4 -3) forms a parallelogram find the value of 'a:​

Answer 1

Answer:

a=7

Step-by-step explanation:

the given fig is a parallelogram

hence opposite sides will be equal . their midpoint will also be equal

hence    x1+ x2/2 of AB = midpoint of BC

1+2/2= a-4/2

solving further , 6/2 = -4+a

hence a=7
