Question

in the diagram, dg || ep. what additional information would prove that defg is an isosceles trapezoid? de ≅ gf ef ≅ dg ef ≅ gf de ≅ dg

Explanation:

Step1: Recall isosceles trapezoid property

An isosceles trapezoid has non - parallel sides congruent. In trapezoid DEFG with DG || EF, the non - parallel sides are DE and GF.

Step2: Identify correct option

The condition that would prove DEFG is an isosceles trapezoid is DE ≅ GF.

Answer:

DE ≅ GF
