(1, 3.5 ) and (3, 3.5 )
the endpoints of the midsegment are at the midpoints of DE and DF
using the midpoint formula with D(0, 7), E(2, 0), F(6, 0)
midpoint of DE = [[tex]\frac{1}{2}[/tex](0 + 2),[tex]\frac{1}{2}[/tex](7 + 0)] = (1, 3.5)
midpoint of DF = [[tex]\frac{1}{2}[/tex](0 + 6),[tex]\frac{1}{2}[/tex](7 + 0)] = (3, 3.5)
