Try looking up each of the shapes and find the one with only one set of parallel lines. The ones with two or more sets of parallel lines are the wrong answer.
To determine the shape of Erica's poster, we need to understand the properties of each of the given options.
A square is a quadrilateral with four equal sides and four right angles. All sides are parallel, not just one pair.
A rhombus is a quadrilateral with all sides of equal length. However, it doesn't have to have parallel sides.
A rectangle is a quadrilateral with four right angles. It has two pairs of parallel sides.
A trapezoid is a quadrilateral with at least one pair of parallel sides. Erica's poster has only one pair of parallel sides, so it is a trapezoid.
Therefore, the correct answer is D. trapezoid.
