Question

given only the information in the image, what is the best description of quadrilateral dear? de||ra m∠e = 120° m∠r = 60° isosceles trapezoid not a trapezoid trapezoid not enough information to decide

Explanation:

Step1: Recall trapezoid definition

A trapezoid has one pair of parallel sides. Here $\overline{DE}\parallel\overline{RA}$.

Step2: Analyze angle - side relationships

We know two non - parallel side angles ($\angle E = 120^{\circ}$ and $\angle R=60^{\circ}$), but no information about side lengths for isosceles property. Since there is one pair of parallel sides, it is a trapezoid.

Answer:

C. Trapezoid
