Question 871183: Dear Math Tutor,
Please help me with: The points A(1,2), B(3,5), C(6,6) and D form a parallelogram. Find the coordinates of the midpoint AC. Use your answer to find the coordinates of D.
The midpoint of AC: (1+6)/2, (2+6)/2 = (7/2,4)
How do I use the midpoint to find coordinates of D now? Whats the methods and processes?
With Gratitude,
Nats
