Question

The fourth vertex D of a parallelogram ABCD whose three vertices are A(-2, 3), B(6, 7) and C(8, 3) is: 1. (0, 1) 2. (0, -1) 3. (-1, 0) 4. (1, 0)

KnowledgeBoat · Accepted Answer

In a parallelogram, the diagonals bisect each other. Therefore, the mid-point of AC = mid-point of BD. By mid-point formula, (x, y) = Substituting values, we get : For diagonal AC: Let point D be (x, y). For diagonal BD: D = (x, y) = (0, -1). Hence, Option 2 is the correct option.
