There are four points a, B, C and D on the rectangular coordinate plane, where a (2,0), B (3,4) and C (6,5). If the quadrilateral a, B, C and D constitute a parallelogram, calculate the coordinate of point D

There are four points a, B, C and D on the rectangular coordinate plane, where a (2,0), B (3,4) and C (6,5). If the quadrilateral a, B, C and D constitute a parallelogram, calculate the coordinate of point D

AC midpoint abscissa: (6 + 2) / 2 = 4
Ordinate: (0 + 5) / 2 = 2.5
So AC and BD midpoint coordinates (4,2.5)
D point abscissa: (3 + x) / 2 = 4, we can get x = 5
Ordinate: (4 + y) / 2 = 2.5, y = 1
So point d coordinates (5,1)
