Question

Given a line ABCD in which AB = BC = CD, B= (0, 3) and C = (1, 8)

Find the co-ordinates of A and D.

Answer 1

Given, AB = BC = CD

So, B is the mid-point of AC. Let the co-ordinates of point A be (x, y).

Thus, the co-ordinates of point A are (-1, -2).

Also, C is the mid-point of BD. Let the co-ordinates of point D be (p, q).
