If the points and are three consecutive vertices of a parallelogram, then its fourth vertex is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
We have a parallelogram ABCD, whose vertices are A2,4,-1, B3,6,-1, C4,5,1 Now, assume the fourth vertex Dx,y,z So, we have diagonals AC and BD Now, we know that, diagonals of a parallelogram bisect each other, So, coordinate of E, as mid-point of AC is…
