Question

in the diagram, dg || ef. what additional information would prove that defg is an isosceles trapezoid? de = gf de = dg ef = dg ef = gf d(-2,2) g(1,2) e(-4,-3) f(3,-3)

Explanation:

Step1: Recall isosceles trapezoid property

An isosceles trapezoid has non - parallel sides equal. In trapezoid DEFG with \(DG\parallel EF\), the non - parallel sides are \(DE\) and \(GF\).

Step2: Identify correct option

We need \(DE = GF\) to prove it's an isosceles trapezoid.

Answer:

\(\overline{DE}=\overline{GF}\)
