Question

given only the information in the image, what is the best description of quadrilateral dear?
de||ra
m∠e = 120°
m∠r = 60°
quadrilateral
trapezoid
parallelogram
isosceles trapezoid

Explanation:

Step1: Recall definitions

A quadrilateral is a 4 - sided polygon. A trapezoid has one pair of parallel sides. A parallelogram has two pairs of parallel sides. An isosceles trapezoid is a trapezoid with non - parallel sides equal.

Step2: Analyze given info

We know that $\overline{DE}\parallel\overline{RA}$. There is no information about the other pair of sides being parallel or the non - parallel sides being equal. So, with only one pair of parallel sides, it is a trapezoid.

Answer:

B. Trapezoid
