The midpoint of each diagonal of ABCD is (6, 3), and (6, 4)
A quadrilateral is a shape with 4 sides
The diagonal of the Quadrilateral ABCD with vertices at: A(0,7), B(10,9), C(12,-1), and D(2-3) has a diagonal of AC and BD
Midpoint is the point that divides two coordinates
Get the midpoint of AC and BD
AC = (0+12)/2, (7-1)/2
AC = (12/2, 6/2)
AC = (6, 3)
Similarly for BD
BD = [(10+2)/2, 9-1/2]
BD = (12/2, 8/2)
BD = (6, 4)
Hence the midpoint of each diagonal of ABCD is (6, 3), and (6, 4)
