See explanations below
Explanation:
Given the quadrilateral ABCD
A(3,0),B(-4,4),C(-7,0) and D(-3,-5)
The sides of the quadrilateral are AB, BC, CD and AD
The midpoint coordinate of the line is expressed as;
X = x1+x2/2
Y = y1+y2/2
Given A(3,0),B(-4,4)
Midpoint of AB = (3-4/2, 0+4/2)
midpoint of AB = (-0.5, 2)
Given B(-4, 4),C(-7, 0)
Midpoint of BC = (-4-7/2, 4+0/2)
midpoint of BC = (-11/2, 4/2)
Midpoint of BC = (-5.5, 2)
Given C(-7, 0) D(-3,-5)
Midpoint of CD = (-7-3/2, 0-5/2)
midpoint of CD = (-10/2, -5/2)
Midpoint of CD = (-5, -2.5)
Given A(3,0),D(-3, -5)
Midpoint of AD = (3-3/2, 0-5/2)
midpoint of AD = (0/2, -5/2)
Midpoint of AD = (0, -2.5)
