If A(-2, 1), B(a, 0), C(4, b) and D(1, 2) are the vertices of a parallelogram ABCD
Coordinate Geometry (10)If A(-2, 1), B(a, 0), C(4, b) and D(1, 2) are the vertices of a parallelogram ABCD, find the values of a and b. Hence find the lengths of its sides.
Answer
ABCD is a parallelogram. Therefore, diagonals AC and BD bisect each other.
Therefore, mid point of BD is same as mid point of AC.
